Claim TODO tasks with [-]; promote mockups to assets/images/ui

- AGENTS.md now requires agents to mark a task [-] while claimed/in progress and
  only use [x] after implementation and verification, with an example
- copied the 21 reference mockups from docs/screens/designs/ into the runtime
  root assets/images/ui/ (byte-identical names); docs/screens/designs/ stays as
  the reference-only copy per ADR-0014
- MEMORY records where the copies live and that screen_designs.py still reads
  the docs tree until the code-path migration

First storage-restructure TODO item completed.

+- **Realism pass tooling (2026-11-01):** `tools/scene_concepts.py` (`list`/`generate`/`process`/
+  `audit`/`realism`) never overwrites an image (`next_free_path` adds `-vN`; `process` skips
+  existing targets). Raw AI output: `assets/textures/ai/v2/raw/` (gitignored). Candidate pool:
+  `assets/textures/ai/game_ready/v2/` (gitignored except the validated picks un-ignored in
+  `.gitignore`: skyline day-v4/dusk-v3/night-v4 plus brick/pavers/asphalt/asphalt_wet + normals).
+  Concepts: `docs/screens/concepts/` (committed, `.gdignore`, targets in its README). Runs:
+  `docs/screens/realism/<run>/` (PNG captures gitignored; `report*.{json,md}` + `sheet.jpg`
+  committed). `src/test/capture_realism.gd` swaps textures at runtime by the material's

+  garbled "HOLLYWOOD" lettering unless the prompt forbids signs. Skyline strips are 2:1 to match
+  one UV repeat of the ring. `elapsed_s = 620` gives the *Evening* phase (pink sky), not night.
+  The gemini-flash-lite realism scores are noisy (±1–2), and the judge sometimes returns a 400
+  "API key not valid" from the provider, which the one retry covers. None of the v2 assets are
+  wired into the game yet.
