Finish the image-root task and untrack Blender sources

- ignore assets/models/blender_src/*.blend (keep the .gdignore marker tracked) and
  remove the 46 editable .blend files from the index; they remain on disk and are
  regenerated by tools/blender_assets.py
- move the completed storage/docs/code-path/art-loader/verification, mouse-fix,
  and pop-up sections to DONE.md; TODO now holds only the open lighting item,
  realism follow-ups, and optional ideas
- docs changes only; runtime code unchanged

+## Visual Alignment — UI Paths and Art Loader
+
+Completed 2026-11-01.
+
+
+### Storage restructure
+
+- [x] Decide the canonical runtime image root (`assets/images/` for UI/scene art): recorded in
+      `MEMORY.md` and [ADR-0014](docs/adr/0014-runtime-image-root.md).
+- [x] Move the reference mockups from `docs/screens/designs/` into the runtime root (keep `docs/screens/designs/` as a docs-only copy or replace it with the new path).
+- [x] Document one convention for game vs reference vs development images across `assets/textures/`, `assets/images/`, `assets/models/generated/`, `docs/screenshots/`, and `docs/screens/designs/` (in `docs/architecture.md`, ADR-0014).
+- [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.
+- [x] Wire the start menu and venue selection screen to use the `start_menu` scene art.
+- [x] Wire the pause overlay to `pause_overlay` scene art (backdrop + opaque panel cover).
+- [x] Wire the settings panel to `settings_panel` art.
+- [x] Wire the shift-review screen to `shift_review` art (backdrop + opaque panel cover).
+- [x] Wire the wand popup to `wand_screening` art.
+- [x] Style the radial menu and finish the remaining HUD chrome against their reference images.
+
+
+### 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).
