Stage 1 of the "full retail inventory" arc (Stage 2 = paperdoll, separate
spec). Grounded in the dat dumps: contents grid 0x100001C6 is 192x96 (6x3) +
scrollbar 0x100001C7 (16x96); backdrop 0x100001D0 is full-window 300x362
(so the "torn" look is the unclipped grid overflowing below the frame —
fixed by clipping); side-bag column 0x100001CA is 36x252 (7 slots).
Components: (A) UiItemList clip+scroll reusing UiScrollable + bind the gutter
scrollbar like ChatWindowController; (B) backdrop coverage — primary fix is A,
residual gated on the post-A screenshot; (C) side-bag column pads empty slots
up to capacity at 36px pitch. Paperdoll + B-Drag out of scope.
