 - [x] Re-run `godot --headless --path . --import` to regenerate `.import` sidecars after any move.
 - [x] Confirm `.gitignore` still excludes development-only outputs (concepts, Blender sources, raw AI fabrics) under the new layout; Blender `.blend` sources are now untracked and ignored.
 
-
 ### Documentation path updates
 
 - [x] Update `README.md` paths (screen-designs section, confirmed-assets links, the `assets/images/scenes` resize example).
 - [x] Update `docs/architecture.md`, `PLAN.md`, and ADR references: docs/screens/designs/ is now explicitly the reference-only snapshot; runtime art lives in assets/images/ (ADR-0014).
 - [x] Update `tools/screen_designs.py` docstrings and mark the old paths in `DONE.md` as historical.
 
-
 ### Code path updates
 
 - [x] Point `tools/screen_designs.py generate` at the new design output path and keep `compare`/`judge` reading the right locations.
 - [x] Update GDScript `preload()` paths if game textures move (no runtime material/model textures moved; UI art added under assets/images/).
 - [x] Update capture output directories if captures relocate (none did; QA captures stay in docs/screenshots/).
 
-
 ### Load proposed interfaces + scene art from disk
 
 - [x] Add a central UI/scene art loader (e.g. `src/game/ui/art.gd`) that loads the mockup-derived images from the new runtime root, with a procedural fallback when a file is missing.

 ### Verify against the mockups
 
 - [x] Regenerate the staged captures and run `screen_designs.py compare` (11 good, 0 bad; verified in a clean HEAD worktree).
 - [x] Run `screen_designs.py judge` and clear every `diff` verdict (7 match, 4 review, 0 diff).
 - [x] Add the capture + compare step as a repeatable smoke so drift is caught early (`tools/check_screenshots.sh`).

 ## Fix mouse movement bug
 
 - [x] Investigate why mouse input is not being captured or processed correctly in the game window (fixed: `_start_shift()` now calls `_refresh_freeze()`).

 ## Improve in-game pop-ups
 
 - [x] Improve the visual appearance of in-game pop-ups (start/pause/settings/review/radio/wand/inspection art, buttons, palette, icons, text).
