the world map's arrow shows on zone sheets, and UIParent goes stock

- the world map's arrow shows on every zone sheet, and alt-clicking a town jumps there: the stock file creates the player arrow as a `Model` child of `WorldMapFrame` and lays a zone sheet's explored-area overlays as ARTWORK textures on `WorldMapDetailFrame` — one `(strata, level)` bucket, where the draw layer outranks the frame — and benilla drew a model's scene at the frame's own layer-0 slot, so every overlay painted over it (the continent sheet has no overlays, which is why it was the only sheet with an arrow); wow-re's carve: a layer batch carries three sub-arrays — quads, the string batch, a render-callback list — that `0x76fb00` drains in that order, and `0x76d160` registers a model's callback only for layer 2 (`0x76d17f cmp ebx,2`), so a model's scene is ARTWORK content, neither a separate pass nor a layer-0 slot; a `ModelPane` quad now keys at the ARTWORK content rank, which re-orders the pet page's happiness icon (a sibling's BACKGROUND quad) under the pane's scene — the reference's own order, harmless because the bake is transparent where the model is not; a model against a LATER-linked ARTWORK font string in the same bucket is still ordered by link stamp, named not built; and the alt-click jump, which required the topmost frame under the cursor to be `WorldMapButton` itself while the stock file parents every POI icon and blip to that button, now walks up from whatever was hit to the button and takes its rect — the map's own chrome still answers nothing (1992)
- `UIParent` is the reference's own: `UIParent.xml` loads off the chain at its toc's slot, right after `WorldFrame.xml`, sourcing `UIParent.lua` and `LocaleProperties.lua` itself, and our `UIParent.xml` + `UiPanels.xml` — 3086 lines of transcribed `UIParent.lua` — are deleted; the one unbound verb the stock file ticks, `CheckReadyCheckTime`, was already 1989's; back from the reference: all sixty-six registered events and their arms (`PLAYER_CONTROL_LOST`/`_GAINED`, `RAID_ROSTER_UPDATE`, the trade-request pair, `PLAYER_SKINNED`, `GOSSIP_ENTER_CODE`), the ESC ladder as written — StaticPopup, the options window's Cancel, the game menu, `CloseMenus`, `SpellStopCasting`, `SpellStopTargeting`, `CloseAllWindows`, `ClearTarget`, else open — so ESC no longer clears a held cursor item or cancels the colour picker, two arms ours had grown that the reference does not have; the fade/flash/pulse kits walked from `UIParent`'s own OnUpdate in place of three 1×1 driver frames of ours, so a cinematic's `UIParent:Hide()` stops the walks as it does there; the managed bottom-stack positions without our `UIParent_RegisterManagedPositionListener` extension, which no shipped file registered any more; `LowHealthFrame`/`OutOfControlFrame`; and the `firstTimeLoaded` close on re-show; what stayed ours moved out — the window tab template and its OnUpdate settle (1004's async-measure adapter) and `BENILLA_FALLBACK_ICON` to `ScrollTemplates.xml`, 0561's bag verbs to `ContainerFrameAdapters`, the script log's slot row to its own file, `OptionsFrameCancel = OptionsFrameCloseButton` beside the two options aliases — and the Auction/Inspect/Macro/Talent panel rows, verbatim copies of the LoadOnDemand addons' own registrations, go; the reference also decides that the area spirit healer's dialog accepts on show with one CANCEL button, that losing control closes every window bar the reference's exceptions, and that the bottom-bar clearance reads the saved globals `SHOW_MULTI_ACTIONBAR_1`/`_2` rather than the bars' shown state; three integration binaries that kept private copies of the manifest loader use the shared one now (1988)

+        exact TexCoords, text CENTER +2, the ADD highlight inset 10px). "Disabled" IS "selected"
+        here — PanelTemplates_SelectTab (script kit above) disables the button and shows the
+        *Disabled (= Active) slices. The ref's OnShow text-fit (PanelTemplates_TabResize(0)) runs
+        from OnUpdate here instead — BenillaTabButton_OnUpdate settles once the async text measure
+        lands, then no-ops (the ref's C measure is synchronous; the 115px XML width is just the
+        pre-fit state). Its OnShow *also* sets the highlight width, which is dead code in the
+        reference and dropped here: this highlight is anchored LEFT/RIGHT, and two opposing anchors
+        resolve the size from the span without consulting the width at all (wow-re layout.md,
+        VERIFIED). The small tab now says the same thing the same way (1004).
+
+        **The OnLoad raise and the OnClick are the reference's own, and both were dropped here
+        until decision 1810.** The note that stood in their place said the raise was unnecessary —
+        "the tabs sit below the window art's hit-rect so nothing overlaps them" — and that "OnClick
+        is the instance's to define". Both were true of our own CharacterFrame.xml, and both are
+        false of the reference's, which is the file that runs now:
+
+          - the reference's `PaperDollFrame` is `setAllPoints enableMouse="true"` with a
+            `bottom=45` hit inset, and the reference's tabs are anchored INSIDE the window (CENTER
+            to BOTTOMLEFT +60,+62), so the page's hit rect covers the whole row. Frame levels come
+            out CharacterFrame 1 / PaperDollFrame 2 / tabs 2, later-created winning — the page eats
+            every tab click. `SetFrameLevel(+4)` is what lifts the row out, and is why the
+            reference has it.
+          - stock `CharacterFrame.xml` gives its five tabs only `<OnEnter>`/`<OnLeave>`; the
+            dispatch lives HERE. Without it `CharacterFrameTab4:GetScript("OnClick")` is nil and
+            the character window's tabs do nothing at all.
+
+        The body hardcodes `CharacterFrame`, which reads odd on a shared template until you check
+        the other consumers: the reference's `MerchantFrameTab1/2` and every one of ours
+        (Auction/Friends/Inspect/Mail/Talent) declares its own `<OnClick>`, and an instance's
+        handler REPLACES the inherited one rather than adding to it. So this reaches exactly the
+        window it names, which is the reference's own arrangement.
+
+        Still ours (moved here from UiPanels.xml with 1988 — that file is the reference's
+        UIParent.lua now), and still why this template is not simply sourced off the chain:
+        `Interface\FrameXML\CharacterFrameTemplates.xml` fits its text in `<OnShow>` through
+        `PanelTemplates_TabResize(0)`, which needs the reference's SYNCHRONOUS string measure. Ours
+        lands a frame late, so the fit runs from `BenillaTabButton_OnUpdate` instead and an
+        OnShow-only fit would leave every tab at its pre-fit 115px. That divergence is 1004's, it
+        spans six windows, and it is what this template's own migration waits on.
