    <!--
        The stack-split spinner (decision 0216 §6/§D, scratchpad `ref-framexml/StackSplitFrame.xml`/
        `.lua`, transcribed near-verbatim onto our own cursor seam — `SplitContainerItem`/
        `OpenStackSplitFrame` already exist in benilla-ui's `cursor.rs`; this file is purely the
        window + the Left/Right/Okay/Cancel plumbing around it). One shared instance, like the real
        client's `StackSplitFrame` — any owner (a bag slot today; the paper doll / bank / mail slices
        reuse it unmodified later) sets `owner.SplitStack = function(owner, n) ... end` before calling
        `OpenStackSplitFrame`, and Okay calls it generically (`StackSplitFrameOkay_Click`).

        Textures: `Interface\MoneyFrame\UI-MoneyFrame` (the little parchment plate) and
        `Interface\MoneyFrame\Arrow-Left/Right-Up/Down/Disabled` are the ref's own — both already
        resolve through the shared sprite loader the money-purse coin icons use
        (`Interface\MoneyFrame\UI-MoneyIcons`, BagFrame.xml/MerchantFrame.xml), so they're quoted
        verbatim rather than substituted. The Okay/Cancel button face (`UI-Panel-Button-*`) is our
        own local virtual template, NOT a cross-file `inherits` of `BenillaQuestPanelButtonTemplate`
        (QuestFrame.xml) — this file loads BEFORE QuestFrame.xml (see ui_script/mod.rs's load order),
        so that template isn't registered yet; the house convention already answered this exact case
        for GossipFrame/QuestFrame/QuestLogFrame ("our engine ships no UIPanelButtonTemplate, so we
        draw it") — this is one more independent draw of the same real art.

        NAMED DEFERRALS (both cited on the functions below, not just here):
        - Typed-digit entry (`StackSplitFrame_OnChar`/`_OnKeyDown` in the ref): this engine has no
          plain-frame OnChar/OnKeyDown keyboard capture, only EditBox focus (grepped; no such hook
          exists anywhere in benilla-ui). The Left/Right spinner buttons are the only way to change
          the split count.
        - The ref's shift-click "insert the item link into the chat editbox" (StackSplitFrame isn't
          even opened in that branch — ContainerFrame.lua:568-569 diverts to
          `ChatFrameEditBox:Insert` instead of `OpenStackSplitFrame`) never triggers here: the
          shift-click gesture itself has no plumbing in this engine (BagFrame.xml's own comment on
          `BenillaBagSlot_OnClick` — no modifier-key global exists at all), so there is no path that
          reaches this branch to defer. `EditBox:Insert` DOES exist on our engine (editbox.rs) for
          when that gap closes.
