Remove third compare tooltip support

Drop legacy third shopping tooltip handling from GameTooltip_ShowCompareItem. Unpack only two shoppingTooltips, remove unused item3/shoppingTooltip3 variables and commented code, and simplify anchor/owner logic for the two-compare layout. GAP/backdrop spacing calculation is preserved.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+## ~~97. Lift GameTooltip's 30-line cap~~ — DONE
+
+Shipped as [src/tooltip/LinePool.cpp](src/tooltip/LinePool.cpp): pure C++,
+no addon Lua. Co-hooks the XML-OnLoad region scan (FUN_00529650, vtable
+slot 9) via `Game::HookAutoRegister`; after the engine sets up the
+template's 30 lines it creates `TextLeft/Right 31..60` in C++ (alloc →
+ctor → name → font-copied-from-prev → anchor, offsets scaled pixel →
+internal like Script_SetPoint) and appends them to the tooltip's three
+line arrays, bumping `numLinesAllocated`. Runs once per GameTooltip-family
+frame at creation + per `/reload`, so it auto-covers GameTooltip,
+ShoppingTooltip1/2, ItemRefTooltip, AtlasLootTooltip, WorldMapTooltip, …
+Verified in-game: AtlasLoot tooltip rendered a 31st line correctly. Cap is
+`kMaxLines = 60`. The design notes below record the RE trail; Approach A
+(hook AddLine) / Approach B (addon Lua) were both explored and dropped in
+favor of the scan-hook.
+
+Vanilla 1.12's `GameTooltip:AddLine` silently drops any line past the
+pool of `TextLeftN`/`TextRightN` FontStrings the XML template
+pre-declares (30). Modern (3.3.5+) engines grow the pool on demand.
+Addons that append comparison summaries, item-info footers, or aura
+details to a full item tooltip get their tail chopped. Practical
+example — pfUI's eqcompare block (base-stat deltas inline + extended
+stats appended at the bottom) hits the cap on stat-heavy items where
+the vendor tooltip already has ~22 lines and the compare block adds
+another 10; extended-stat rows past line 30 disappear silently.
+
+Also affects `ShoppingTooltip1`/`ShoppingTooltip2` (same
+`GameTooltipTemplate`).
+
+### Root cause (verified in Ghidra on the 1.12 Octo binary)
+
+`AddLine` internal impl at `FUN_00530270` — the shared body called
+from both `Script_GameTooltipAddLine` (`FUN_00531630`, method ptr
+stored in the GameTooltip method table alongside the `"AddLine"`
+string at `0x00854560`) and `Script_GameTooltipAddDoubleLine`:
+
+```c
+void FUN_00530270(int this, char *leftText, char *rightText,
+                  colorLeft, colorRight, wrapFlag) {
+    if ((*(int *)(this + 0x31c) != *(int *)(this + 0x320)) && anyHasText) {

+        // wrapFlag[numLines_used] = wrapFlag,
+        // ++numLines_used
+    }
+    // else: silently drop the line
+}

+### CGameTooltip struct offsets (1.12)
+
+Derived from `FUN_00530270` and the pool-init at `FUN_00529650`:
+
+| Offset | Field                                              |
+|--------|----------------------------------------------------|
+| `+0x31c` | `numLines` — current write index (0-based)       |
+| `+0x320` | `numLinesAllocated` — pool size (30 default)     |
+| `+0x328..+0x32c` | `textLeft[]` — array of `CSimpleFontString *`, count `+0x320` |
+| `+0x334..+0x338` | `textRight[]` — same, symmetric right column |
+| `+0x340..+0x344` | `wrapFlag[]` — per-line wrap bool           |
+
+Actual layout of the array slots: `+0x328` is the first ptr in an
+external heap block whose base is `param_1[0xcb]` = `+0x32c`. The
+init function reallocates all three arrays whenever `numLinesAllocated`
+would change — see `FUN_00536c80` (the reallocator) and `FUN_004368c0`
+(a matching alloc for the wrap-flag array of a different element size).
+
+### The pool-init function
+
+`FUN_00529650` — walks `%sTextLeftN` / `%sTextRightN` FontString names
+from the FrameXML-declared pool, counts them, reallocates the three
+arrays, stores the pointers. Called via vtable slot at `0x00808f84`
+(only xref) — likely `SetOwner` or an equivalent virtual reset method
+runs it. It's the natural growth path — if we can force it to see a
+larger pool of Lua-visible FontStrings and trigger it, the arrays
+resize themselves.
+
+### The 3.3.5 reference (already REd)
+
+3.3.5's `GameTooltip::AddLine` at `0x0061fec0` has the grow-on-demand
+branch we want to backport. Shape:
+
+```c
+if (currentLine == numLinesAllocated - 1) {
+    format(buf, 256, "%sTextLeft%d", tooltipName, currentLine + 1);
+    auto *fs = SimpleFontString::create(this, /*layer*/2, /*subLayer*/1);
+    fs->setName(buf);
+    fs->setFontObject(prevLeft->fontObject);
+    fs->anchor(TOPLEFT, prevLeft, BOTTOMLEFT, 0.0, calculatedYOffset);
+    // ... mirror for TextRight ...
+    // ... append fs to textLeft[]/textRight[] at [numLinesAllocated],
+    //     then ++numLinesAllocated.
+}
+// fall through to the existing "set text on line[currentLine]" path
+```
+
+3.3.5 helpers (offsets 3.3.5-specific — 1.12 equivalents need to be
+re-derived):
+- `FUN_00485240` — SimpleFontString constructor `(parent, layer, sublayer)`
+- `FUN_0048b6c0` — set-name helper (registers under global `_G[name]`)
+- `FUN_0048a260` — anchor helper `(this, anchorPoint, relativeTo, relativePoint, xoff, yoff)`
+
+Struct offsets in 3.3.5 were `+0x2a4` (numLines) / `+0x2a8` (numAlloc) /
+`+0x2b4` (textLeft) / `+0x2c0` (textRight) / `+0x2cc` (wrapFlag). All
+shifted vs. 1.12 (see above), unsurprising given TBC/WotLK bloat.
+
+### Implementation plan
+
+**Approach A — pre-hook AddLine with a grow-if-needed prelude
+(preferred)**:
+
+1. Locate the 1.12 equivalents of the three 3.3.5 helpers. Trace them
+   from existing `CSimpleFontString`-creating sites in the engine —
+   the CreateFontString API dispatch is a good starting point (it's
+   Lua-visible and calls the same constructor).
+2. Locate the array reallocators used by `FUN_00529650`
+   (`FUN_00536c80` for the two pointer arrays, `FUN_004368c0` for the
+   wrap-flag byte array).
+3. MinHook `FUN_00530270`. Pre-hook body:
+   - If `numLines != numLinesAllocated`, call original — done.
+   - Otherwise: realloc the three arrays to `numLinesAllocated + 1`,
+     create two new `CSimpleFontString` (left + right), name them
+     `"%sTextLeft%d"` / `"%sTextRight%d"` with `tooltip->GetName()` and
+     the new index, anchor each below the prior-slot FontString on the
+     same side, use the prior FontString's `fontObject` (`+0xd8` in the
+     3.3.5 layout — confirm on 1.12) as the default, write the pointers
+     into `textLeft[numLinesAllocated]` / `textRight[numLinesAllocated]`,
+     zero-init `wrapFlag[numLinesAllocated]`, and bump
+     `numLinesAllocated`.
+   - Then tail-call the original — it now succeeds normally.
+
+**Approach B — pre-declare a wider pool via Lua** (fallback if the
+constructor helpers turn out to be too tangled):
+
+1. In `!!!ClassicAPI` addon, at load time, call
+   `GameTooltip:CreateFontString("GameTooltipTextLeft" .. i, "ARTWORK",
+   "GameTooltipText")` for `i = 31..60`, plus `TextRightN`, plus set
+   anchors matching the pattern in the template.
+2. Force the engine's pool-init to re-scan. If we can't reach the
+   vtable trigger cleanly, expose a small C entrypoint that walks the
+   pool the same way `FUN_00529650` does — takes `tooltip` as arg,
+   reallocates arrays, refills.
+
+Approach B is less code but ties the cap to a fixed number (60 lines
+is enough for pfUI's use case but arbitrary). Approach A grows on
+demand like retail and has no ceiling.
+
+### Testing
+
+- Hover a random-suffix weapon with several equip-spell bonuses (Krol
+  Blade, Ironfoe, any ZG/AQ trinket) — tooltip should render >30 lines
+  without truncation.
+- Hover an item that produces a 40+ line tooltip when pfUI's eqcompare
+  block is enabled (Priest Judgement Set chest against another
+  Judgement chest: item tooltip ~22 lines + compare block ~10 lines).
+- Verify no crash / no visual glitches on:
+  - ShoppingTooltip1/2 (same class, same `GameTooltipTemplate`)
+  - Rapid re-hovers (create/destroy pressure on the added FontStrings)
+  - Item tooltips that stay under 30 lines (pre-existing behavior unchanged)
+
+### Risks
+
+- If the array reallocation logic in `FUN_00536c80` doesn't null-out
+  the tail on grow, `textLeft[N]`/`textRight[N]` might contain
+  garbage for a frame — anchor before write, or memset to zero.
+- FontString lifetime: 3.3.5 leaks the extras for the tooltip
+  lifetime (they stay hidden when unused). GameTooltip is a
+  singleton, so leak is bounded. Fine.
+- Interaction with `pfUI`'s existing tooltip skinning (frame borders,
+  status bar reposition, etc.): the layer we're modifying is beneath
+  the skinning; shouldn't touch anything visible unless anchor math
+  is wrong.
+
+### Related
+
+If we ever consider dropping the whole "GameTooltipTemplate declares
+30 FontStrings in XML" scheme and instead having the engine start
+with 0 and grow entirely on demand — that would be even cleaner, but
+requires patching every consumer of the initial pool (there aren't
+many, but they need audit). Filed for future if the incremental grow
+turns out to be fragile.
+
+### Investigation update (resolved unknowns)
+
+Traced the pool machinery end-to-end. The open questions above are now
+answered, and they point away from both the AddLine hook (Approach A)
+and the "trigger the engine's scan" idea — a **hybrid** is cleaner than
+either.
+
+**The scan is virtual slot 9, run only at XML-template instantiation.**
+`FUN_00529650` is slot 9 (`vtable+0x24`) of the CGameTooltip vtable
+(base `0x00808f60`; the null at `0x00808f5c` is the boundary, and slot 2
+`0x005368d0` is the `tooltip:method()` dispatcher — confirms the class).
+The two vtable-base xrefs are the constructors `FUN_00529240` /
+`FUN_00529480`. The scan's prologue calls
+`FUN_0076a2f0(node) → FUN_0076a060(node)`, which reads the XML
+`"inherits"` attribute and child `"Frames"` — i.e. the scan is the
+frame's **XML OnLoad / region-setup** virtual. It runs once when
+`GameTooltip` is built from `GameTooltipTemplate` (and again per
+`/reload`), **not** on `SetOwner`/show. So we can't cheaply re-trigger
+it — the `node` arg is a live XML-parse handle we don't have, and
+calling it with a bogus node runs the inherits/Frames path on garbage.
+
+**The scan finds lines by `_G[name]`, so Lua-created FontStrings count.**
+`numLinesAllocated` (`+0x320`) is literally "how many contiguous
+`%sTextLeftN` **and** `%sTextRightN` exist by name": pass 0 counts (stop
+at the first missing index), pass 1 reallocs the three arrays to that
+count and fills the pointers. The name lookup `FUN_0076c760` does
+`lua_pushstring(name); gettable(_G); if type==TABLE: FrameScript_GetObject`
+— a plain `_G[name]` resolve, so a FontString made with
+`GameTooltip:CreateFontString("GameTooltipTextLeft31", …)` **is**
+visible to it. (Names must be contiguous and exist in *both* columns.)
+
+**The array reallocators are simple and callable from C.**
+`FUN_00536c80` (pointer arrays) and `FUN_004368c0` (wrap-flag array) are
+the same routine with different SMem tags:
+`__thiscall(descriptor, newCount)` where the descriptor is
+`{ count@+0x0, cap@+0x4, data@+0x8 }` — reallocs `data` to `newCount*4`
+and copies the old contents. In the tooltip the three descriptors are:
+
+| Descriptor `this` | count / cap / data | array |
+|-------------------|--------------------|-------|
+| `tooltip + 0x324` | `+0x324 / +0x328 / +0x32c` | `textLeft[]`  (`CSimpleFontString*`) |
+| `tooltip + 0x330` | `+0x330 / +0x334 / +0x338` | `textRight[]` |
+| `tooltip + 0x33c` | `+0x33c / +0x340 / +0x344` | `wrapFlag[]`  (int, 4-byte) |
+
+`numLinesAllocated` (`+0x320`) is a separate field the scan sets equal
+to the count; AddLine (`FUN_00530270`) gates on
+`numLines(+0x31c) != numLinesAllocated(+0x320)`.
+
+**Recommended approach — Lua creates FontStrings, C grows the arrays
+(no hook, no XML re-run).** Replicate the scan's pass 1 directly:
+
+1. **Lua (`!!!ClassicAPI`), at load / `PLAYER_LOGIN`:** for each frame on
+   `GameTooltipTemplate` (`GameTooltip`, `ShoppingTooltip1/2`,
+   `ItemRefTooltip`, …), create `<name>TextLeft31..N` and
+   `<name>TextRight31..N` via `frame:CreateFontString(nm, "ARTWORK",
+   "GameTooltipText")`, each anchored `TOPLEFT`/`TOPRIGHT` to the prior
+   line's `BOTTOMLEFT`/`BOTTOMRIGHT` (mirror the template's chain).
+   This avoids re-deriving the 1.12 FontString ctor / setName / anchor
+   helpers that Approach A needed — Lua already wraps them.
+2. **C entrypoint** `GrowTooltipPool(tooltipObj, newCount)` (expose as a
+   Lua global, called once per frame right after step 1):
+   - `FUN_00536c80(tooltip+0x324, newCount)`; set `+0x328 = newCount`.
+   - `FUN_00536c80(tooltip+0x330, newCount)`; set `+0x334 = newCount`.
+   - `FUN_004368c0(tooltip+0x33c, newCount)`; set `+0x340 = newCount`.
+   - for `i` in `[oldAlloc, newCount)`: resolve `<name>TextLeftN`/
+     `RightN` via the `_G[name]` dance (same as `FUN_0076c760`), and if
+     either is missing stop at `i`; else write the two pointers into the
+     new `textLeft`/`textRight` data slots and zero `wrapFlag[i]`.
+   - set `numLinesAllocated (+0x320) = i`.
+   Resolve `tooltipObj` from the Lua frame the same way our other
+   tooltip methods do (`FrameScript_GetObject`).
+
+Runs once per frame per session (re-runs on `/reload`, which recreates
+the frames → scan resets to 30 → our addon re-creates + re-grows). No
+per-line hook (dodges the MinHook-collision risk on a moderately hot
+function), no XML-node fabrication.
+
+Remaining risk to validate in-game: whether AddLine's downstream layout
+/ `Show` sizing walks `numLines` FontStrings by their anchors (expected)
+vs. any hidden fixed-30 assumption elsewhere; and that the Lua-created
+lines inherit height/spacing identical to the template's 1..30 so the
+tooltip grows seamlessly. Both are observable on the first >30-line
+hover.

 GameTooltip:Show()

+### `GameTooltip:SetHyperlinkCompareItem("itemLink" [, offset, shiftButton, comparisonTooltip])`
+
+Fills the tooltip with the item **currently equipped** in the slot the
+given item would occupy — a grey `Currently Equipped` header, the
+equipped item's own tooltip, then (when `shiftButton` is set) a
+green/red per-stat delta breakdown of how the given item compares.
+This is the method behind item-comparison ("shopping") tooltips;
+`FrameXML`'s `GameTooltip_ShowCompareItem` drives it.
+
+Call it on the tooltip that should show the comparison (typically
+`ShoppingTooltip1`/`ShoppingTooltip2`, but any `GameTooltipTemplate`
+frame works).
+
+| Arg | Meaning |
+|-----|---------|
+| `itemLink` | The item being compared (chat link, `item:` string, or bare itemID). Optional if `comparisonTooltip` is given. |
+| `offset` | 1-based slot selector for two-slot items — rings, trinkets, and one-hand weapons expose `offset` 1 and 2 (Finger1/2, Trinket1/2, MainHand/OffHand). Default 1. |
+| `shiftButton` | Gates the stat-change breakdown. Deltas show by default (`true`/`1`/`nil`/omitted) and are hidden only for an explicit `false`/`0` (header + equipped item only). Both the boolean and vanilla `1`/`nil` conventions are accepted. |
+| `comparisonTooltip` | Optional. When `itemLink` is omitted, the compared item is taken from whatever this tooltip is displaying (matches the retail tooltip-to-tooltip call). |
+
+**Returns** the number of comparison slots for the item (1, or 2 for
+rings/trinkets/one-hand weapons; 0 if it isn't equippable, isn't
+cached, or nothing is equipped in the chosen slot) — so a caller knows
+whether a second `offset` is worth querying.
+
+The stat deltas cover the same keys as
+[`C_Item.GetItemStats`](#c_itemgetitemstatsitemlink) (base stats,
+resistances, weapon DPS, and on-equip-spell bonuses like crit / attack
+power / spell power), colored with the client's
+`INCREASE_STAT_COLOR` / `DECREASE_STAT_COLOR`. The method only
+populates the tooltip; the caller shows/anchors it (as retail's
+`SetHyperlinkCompareItem` does).
+
+```lua
+-- Compare a hovered bag item against what's equipped:
+local link = GetContainerItemLink(bag, slot)
+ShoppingTooltip1:SetOwner(GameTooltip, "ANCHOR_NONE")
+local slots = ShoppingTooltip1:SetHyperlinkCompareItem(link, 1, true)
+ShoppingTooltip1:Show()
+if slots == 2 then  -- ring/trinket/1H: also compare the other slot
+    ShoppingTooltip2:SetOwner(GameTooltip, "ANCHOR_NONE")
+    ShoppingTooltip2:SetHyperlinkCompareItem(link, 2, true)
+    ShoppingTooltip2:Show()
+end
+```
+
+### `GameTooltip:IsEquippedItem()`
+
+Returns `true` when the item the tooltip is **currently displaying** is
+equipped in one of the player's character-pane slots (1..19). Backports
+the 3.3.5 `GameTooltip:IsEquippedItem` method.
+
+Works regardless of how the tooltip was populated — link paths
+(`SetItemByID`, `SetHyperlink`) and CGItem paths (`SetInventoryItem`,
+`SetBagItem`, `SetItemByGUID`, …) both resolve to the displayed item.
+Returns `false` for a tooltip that isn't showing an item (e.g. a spell
+tooltip) with no false positives.
+
+```lua
+GameTooltip:SetInventoryItem("player", INVSLOT_HAND)
+if GameTooltip:IsEquippedItem() then ... end  -- true
+
+GameTooltip:SetBagItem(0, 1)
+if GameTooltip:IsEquippedItem() then ... end  -- false unless that item is also worn
+```
+
+### `OnTooltipSetItem` script
+
+A real frame script — settable with the standard `SetScript` / `GetScript` /
+`HookScript` — that fires whenever a tooltip's **item** is set. Backports the
+modern tooltip script so addons annotate item tooltips by hooking one script
+instead of wrapping every `Set*` method.
+
+Fires for every item-setting path (`SetBagItem`, `SetInventoryItem`,
+`SetHyperlink` for an `item:` link, `SetMerchantItem`, `SetAuctionItem`,
+`SetItemByID`, …). Available on all GameTooltip-type frames (`GameTooltip`,
+`ItemRefTooltip`, `ShoppingTooltip1/2`, `AtlasLootTooltip`, …).
+
+The handler receives the tooltip as the **global `this`**, the 1.12
+frame-script convention — *not* a `self` argument (like every built-in vanilla
+script: `OnShow`, `OnEvent`, `OnTooltipCleared`, …). Modern-style
+`function(self) self:… end` handlers will see `self == nil`; use `this`.
+
+```lua
+GameTooltip:HookScript("OnTooltipSetItem", function()
+    local name, link, id = this:GetItem()   -- the tooltip is the global `this`
+    if id then
+        this:AddLine("ID: " .. id, 0.6, 0.6, 0.6)
+    end
+end)
+```
+
+Vanilla only shipped `OnTooltipAddMoney` / `OnTooltipCleared` /
+`OnTooltipSetDefaultAnchor`; `OnTooltipSetSpell` / `OnTooltipSetUnit` are not
+yet provided.
+
+**Caveat — the event fires from inside the item-tooltip build.** Lightweight
+handler work is fine: reading `this:GetItem()`, `this:AddLine(...)`, printing,
+etc. But avoid *re-entrant* tooltip rebuilds from the handler — e.g.
+`GameTooltip_ShowCompareItem()`, or a `Set*` call on another tooltip. Because
+the handler runs mid-build, re-entering the tooltip / FrameScript machinery can
+collide with other DLLs that hook the same Lua paths (nampower, SuperWoW,
+weirdutils, …) and crash the client. If you need heavy work like that, defer it
+to the next frame:

+Same key set, accepted input forms, random-suffix handling, and caching
+caveat as [`C_Item.GetItemStats`](#c_itemgetitemstatsitemlink) — see
+there for the details. Returns `nil` if **either** item is uncached.
+
+### `C_Item.GetItemStats(itemLink)`
+
+Returns a table of an item's stats, keyed by the FrameXML global-string
+names WoW's own `GetItemStats` uses (so `_G[key]` yields the display
+label — `_G["ITEM_MOD_STRENGTH_SHORT"]` → `"Strength"`). Only stats the
+item actually carries are present.
+
+```lua
+C_Item.GetItemStats("item:2244")            -- Krol Blade
+-- { ITEM_MOD_STRENGTH_SHORT = 7, ITEM_MOD_STAMINA_SHORT = 5,
+--   ITEM_MOD_DAMAGE_PER_SECOND_SHORT = 40.89,
+--   ITEM_MOD_CRIT_MELEE_RATING = 1, ITEM_MOD_CRIT_RANGED_RATING = 1 }
+
+C_Item.GetItemStats("item:12022:0:769")     -- "of the Owl" random suffix
+-- { ITEM_MOD_INTELLECT_SHORT = 6, ITEM_MOD_SPIRIT_SHORT = 6 }
+```
+
+**Sources.** The table is assembled from three places, so it reflects
+what the item actually grants — not just its stored stat slots:
+
+1. **Base record** — the stored attributes, armor, resistances, and (for
+   weapons) DPS.
+2. **On-equip spells** (`SpellTrigger == ON_EQUIP`) — vanilla stores the
+   "special" bonuses (crit, attack power, spell power, hit, mp5, defense,
+   …) as an equip spell whose aura effect carries the value, not as a
+   stat slot. Their auras are decoded into the keys below.
+3. **Random suffix** — the link's third `item:id:enchant:SUFFIX:unique`
+   field (`ItemRandomProperties.dbc` → `SpellItemEnchantment.dbc`): stat
+   suffixes ("of the Owl") are themselves equip spells, armor suffixes
+   ("of Toughness") are direct resistance enchants. A bare itemID or a
+   suffix-less link contributes nothing here.

+// and value-setter (`FUN_SET_CVAR_VALUE`) so other modules can publish
+// persisted, validated settings (clamped via the change callback and saved
+// to Config.wtf).

+// CVars registered here persist to `WTF\Config.wtf` (the engine forces the
