Close the 0.9.3 UI polish milestone

Add deterministic captures 14-21 for the remaining screen-design states, fix the panel/button layout issues they exposed, and record 21/21 compare and judge results. Bump the source to 0.9.3 and move the completed milestone to DONE.md.

 - Aim-free selection pass (v0.3.0 work, [ADR-0011](adr/0011-aim-free-selection-and-precision-walk.md)): the focus cone ranks candidates by angle then distance, `Tab` and the mouse wheel cycle nearby people nearest-first and pin the selection, right click clears focus with a short re-acquire grace, the HUD reports how many people are in the ring, and holding `Shift` walks at half speed for close work
 
 - Visual alignment: start/venue menu, pause, settings, shift review, radio, wand, inspection, timeline, HUD target chip/escalation bar, and radial menu now use or match their AI references in `assets/images/ui/`. The runtime art loader (`src/game/ui/art.gd`) falls back cleanly when a file is missing. The wand panel lists the guest's carried items, and multiline HUD/wand strings render real line breaks.
+- UI-state capture pass (0.9.3 work): `src/test/capture_ui_states.gd` adds committed captures 14–21 for the start menu, pause, settings, shift review, emergency radio, action wheel, crowd panic and responder arrival. Every one of the 21 catalogue entries now has a current-build capture; `tools/check_screenshots.sh` reports 21 good / 0 bad and the automatic judge reports 21/21 match, 0 diff. Crowd panic and responder arrival are staged presentation frames, not gameplay changes.
 - Realism adoption (post-v0.6.0): v2 per-phase skylines and surface tiles with normal maps, retuned sun/exposure/fog, wet asphalt, denser foliage, a visible additive flashlight beam, and refreshed staging captures. `tools/check_screenshots.sh` is the repeatable capture/compare gate; judge is clean of `diff` verdicts.
 - Input/reliability fixes: selecting a venue releases the start-menu input lock and recaptures the mouse; the body-camera overlay no longer covers the shift status. Mouse look now reads at `_input`, restores capture on window focus/click-back, and the HUD is mouse-transparent. Normal radio reports submit on click; emergency calls still require the hold-to-confirm path.
 - Production-quality pass (v0.9.0): mixer/accessibility settings, audio volume clamping, 24-NPC budget smoke, shortened coat/dress stride, and a unified Godot 4.7.2 CI/local support baseline with documented upgrade/rollback requirements.
