docs: D.2b empty-slot art — close inventory portion of the empty-slot-art issue

Browse source 
Inventory contents grid / side-bag / main-pack empty cells now dat-resolve their
art via ItemListCellTemplate (0x1000000e -> 0x21000037). Paperdoll equip
silhouettes + main-pack icon remain open (Sub-phase C / AP-51).

## Inventory + equipment slots show the wrong empty-slot background art
**Status:** OPEN — MEDIUM (D.2b inventory polish; the immediate next task)
**Status:** INVENTORY PORTION FIXED 2026-06-22 (pending visual gate) — contents grid + side-bag + main-pack empty art now dat-resolved (`ItemListCellTemplate`, commits `b862640`→`edbe5ba`). STILL OPEN: paperdoll equip-slot silhouettes (Sub-phase C) + main-pack backpack icon (AP-51).

**Root cause / status:** `UiItemSlot.EmptySprite` is a single hardcoded default (`0x060074CF`) shared by all empty cells. The inventory/side-bag pack slots need the gm3DItemsUI/gmBackpackUI cell-template (`0x21000037`) empty-state background instead. The equip slots need the `0x10000032` `UIElement_UIItem` registration + per-slot silhouette art (Sub-phase C).
**Resolution (inventory portion, 2026-06-22):** Ported retail's `UIElement_ItemList::InternalCreateItem` (`0x004e3570`) resolver into `ItemListCellTemplate.ResolveEmptySprite` — reads attribute `0x1000000e` off each list element → catalog `0x21000037` prototype's `ItemSlot_Empty`. **Correction to the original diagnosis:** `0x060074CF` is the *generic shared* item-slot empty (the `ItemSlot_Empty` of many catalog prototypes), not "the toolbar's"; `0x21000037` is a catalog of ~50 per-slot-kind empties — so it was never a one-constant swap. Pinned per-list (real-dat test): contents `0x100001C6` → `0x06004D20`; side-bag `0x100001CA` + main-pack `0x100001C9` → `0x06005D9C` (the 36×36 frame). `UiItemList.CellEmptySprite` carries it; `InventoryController` + `GameWindow` wire it. Divergence AP-55 (toolbar still hardcoded) + AP-56 (flat single-sprite cell vs retail's layered prototype). Spec/plan `docs/superpowers/{specs,plans}/2026-06-22-d2b-empty-slot-art*.md`.
**Files:** `src/AcDream.App/UI/UiItemSlot.cs` (`EmptySprite`); `src/AcDream.App/UI/Layout/InventoryController.cs` (set the inventory pack-slot empty sprite on the cells it creates); paperdoll equip slots → Sub-phase C.
**Research:** `.layout-dumps/uiitem-0x21000037.txt` (cell template states); `docs/research/2026-06-16-equipment-paperdoll-deep-dive.md`. Also pending: the main-pack backpack icon (AP-51).
