The last two UI integration files, both resting on `UIPanelWindows` rows the realm changed.
`ItemTextFrame` is `{ area = "left", pushable = 5 }` where 1.12's row was `pushable = 0`. That made
the reader and a quest giver's gossip left-slot rivals which replaced each other and ended each
other's session on the way out; pushable, they share the screen — one takes left, the other slides
to centre, in either order, and neither `CloseItemText` nor `CloseGossip` is queued. The test is
renamed for what it now proves. Its page bodies also pick up the realm's own three trailing
newlines on both arms of the creator fork (`ItemTextFrame.lua:41-46`), where 1.12 wrote two.
`OpenMailFrame` has no `UIPanelWindows` row at all, so `ShowUIPanel` takes its first branch — a
bare `frame:Show()` that claims no slot (`UIParent.lua:920-923`) — and a letter therefore *covers*
the centre occupant instead of evicting it. The eviction runs one way only: the letter is a
`UIChildWindows` member, so the next panel to seat anywhere hides it. And it has to **arrive** to
do that: `ShowUIPanel` returns on its first line for a frame already shown, so asking for the sheet
again while it is up reaches no slot and hides nothing.
Workspace: 191 red → 134, with zero regressions (`comm` against the pre-session list). Every one of
the 57 was in `ui_script` or these two files, and that whole surface is now green: 1113 `ui_script`
tests, `item_text_frame`, `mail_frame`, `message_keys`, `cover_input_wall`, `character_stats`. What
is left is the benilla-formats data goldens, which are documented separately and were red before.
All seven gates green.
