+## Decisions
+
+- Runtime UI/scene art is loaded through `src/game/ui/art.gd` (`assets/images/ui/` then `scenes/`); missing files return null so panels keep procedural fallbacks.
+- Screen mockups with baked-in controls are used as backdrops plus an opaque `ArtPanel` cover, not as clickable full-screen skins.

+## Uncommitted Workstreams

+- A separate realism pass is editing `PLAN.md`, `README.md`, `.gitignore`, `src/game/materials.gd`, `tools/scene_concepts.py`, `tools/test_scene_concepts.py`, `src/test/capture_realism.gd`, `assets/textures/ai/game_ready/v2/`, `docs/screens/concepts|realism/`, and regenerated Blender planter/tree assets. Do not commit or revert these while that pass is active; verify game changes in a clean `git worktree` at HEAD when its unimported textures break parsing.
