+- Staged captures in `docs/screenshots/` are committed and were regenerated on 2026-11-03 with the full `tools/check_screenshots.sh` run (21 good / 0 bad, 13 PNGs changed). Re-run the whole script, never a partial capture, before replacing them. The README, `docs/README.md` quick preview, `docs/screenshots/README.md` and `docs/blender_previews/README.md` now carry captioned galleries; the previews README is curated by hand (all tracked sheets linked, local per-asset PNGs described as untracked).
 - `tools/check_screenshots.sh` is the repeatable capture+compare smoke; both capture scripts accept `--out=res://docs/screenshots`. Judge verdicts on the staged set were 7 match / 4 review / 0 diff.
 - Venue selection used to leave `guard.input_locked` true and the mouse visible; `_start_shift()` must call `_refresh_freeze()` after starting the clock.
