Owner report 2026-09-06: MossTank's shelf icon (0x06002C41) drew with a white
ring. DAT icon art reserves pure-white-opaque pixels as the recolor key that
retail IconData::RenderIcons (0x0058d180) replaces per pixel through
SurfaceWindow::ReplaceColor (0x004415b0) from the effect tile — the solid-black
0x21 tile when there are no effects. The inventory already does this through
IconComposer; the plugin did sink (markup <icon did>, <button icon>, <list icons>
and the shelf button) blitted the art raw.
RetailMarkupIconResolver.ResolveDid now hands out IconComposer.GetKeyedIcon —
the drag-icon composite (base art + effects==0 recolor, no overlay, no
underlay), sharing that cache — so did icons look like a mundane inventory item
does. The resolver no longer needs a TextureCache. KeyedIconInstalledDatTests
pins both halves against the real DAT: the raw art carries the key, the
composite carries none, and ResolveDid returns exactly the keyed composite.
