+## Beute: loot filter (2026-10-19)
+
+The page holds the loot filter (`docs/loot-filter.md`): the game's pickup
+choice (PICKUPAUTO radio buttons, their labels, the separator; matched by
+pointer and control name at +0x30) is never shown, a framed table below the
+auto-pickup frame sets a mode per category. Its frame is made like the key
+page's (`AddFrame`).
