+- ✗ Overlay lists all bindings grouped by context (Map / City /
+  Combat / Menus). Shipped groups are "World Map / Map Overlays /
+  Menus & Panels / Turn Actions" — names differ from the spec and
+  "City" + "Combat" groups are absent (those surfaces have no
+  hotkeys yet). This bullet needs either the spec's exact group
+  set OR user sign-off to renegotiate.
+- ✗ Bindings sourced dynamically from `InputMap.get_actions()` per
+  spec. Shipped: hardcoded `const BINDINGS` table in
+  `hotkey_sheet.gd`. Cannot flip ✓ as specified without migrating
+  all existing keycode-literal handlers to InputMap actions first.
