Bite-sized TDD plan for the stateful item-icon system. Corrects spec 5.8:
the live 0x02CE event binds in GameWindow (next to VitalUpdated), not
GameEventWiring (which only handles the 0xF7B0 GameEvent dispatcher).

Research basis (clean Ghidra decompile via MCP + live-dat probe + ACE oracle)
overturns two handoff hypotheses:
- Appraise carries NO icon/UiEffects data (Icon/IconOverlay/IconUnderlay +
PropertyInt.UiEffects all lack [AssessmentProperty]); every icon input is
CreateObject-only. The "wire appraise -> enrichment" item is a no-op.
- The effect overlay (enum 0x10000005) is a ReplaceColor tint SOURCE, not a
blit layer (RenderIcons 0x0058d180 + ReplaceColor 0x00441530); effect tiles
are 32x32 fully-opaque colored squares.
Design (user-approved): capture UiEffects (weenieFlags 0x80, currently discarded)
-> ItemInstance.Effects; faithful 2-stage IconComposer recolor (white pixels ->
effect hue); live PublicUpdatePropertyInt(0x02CE) wire-up so the icon updates as
state changes ("item with mana vs out of mana"). Drops the appraise no-op.
