Mitigate CI cache timeouts and wire venue door-staff dialogue

- Drop actions/cache@v4 from the checks job: the Gitea runner cannot reach
  GitHub's cache service (/twirp/...CacheService timeouts, ~2min retries);
  Godot import is fast enough without it. Add GODOT_SILENCE_ROOT_WARNING=1.
- Document the cache situation and re-enable path in docs/RELEASING.md
- VenueScenario.door_staff_line(context, rng): seeded-random venue lines
- GameManager logs id/ticket/wand-check, refusal, and prohibited-item lines
  from the venue scenario (Joke Shop flavor) during inspection/screening
- Test coverage: all Joke Shop contexts, unknown contexts, empty venues,
  deterministic seeded picks (54 tests pass)

+## 🔧 CI — cache timeout mitigation (from .gitea/logs/ review)
+
+`actions/cache@v4` times out against GitHub's cache service on this runner
+(`/twirp/github.actions.results.api.v1.CacheService/…` — the Gitea host has no
+local actions-cache configured). Restore/save retry for ~2 min per run. The
+checks job still passes; this is noise + risk of flaky timeouts.
+
+- [x] Remove the `actions/cache@v4` step from `checks` in `.gitea/workflows/build.yml`
+      (Godot import takes ~4s; caching .godot is not worth the timeout risk).
+- [x] Add `GODOT_SILENCE_ROOT_WARNING=1` to godot steps to quiet container-as-root noise.
+- [ ] Push and confirm the next `.gitea/logs/` run has no `CacheService` timeouts.
+- [x] Optional (host admin): document in `docs/RELEASING.md` that `actions/cache` needs a
+      Gitea `[cache.actions]` + cache server before it can be reintroduced.

 ## Open Polish
 
-- [ ] Add venue-specific door-staff dialogue usage (scenario `door_staff_lines` is authored but not yet shown in the prototype UI).
 - [ ] Add a body/wand cooldown feel: wand screening currently has no reuse penalty; consider a short per-guest scan animation.
 - [ ] Add an escape-to-circuit handling note: `signals` in `Strings.fmt` are positional; keep `%` placeholders stable when adding keys.

+## Detailed Graphics
+
+The prototype is entirely procedural `BoxMesh` with flat `StandardMaterial3D` colors (see `src/game/world_builder.gd` and `src/game/npc_avatar.gd`). The items below upgrade it toward a finished look. **When a task needs a texture, sprite, decal, or reference image, use the integrated image-generation function to produce it** (e.g. seamless building facade, sidewalk concrete, asphalt, awning sign, wristband/ID inspection cards, HUD icons). Generated images go under `assets/` and are imported as Godot textures; keep them small (≤1024px) and power-of-two where possible.
+
+### Environment
+
+- [ ] Replace flat facade boxes with textured materials: brick/concrete facade, glass door, awning with a readable sign (generate facade + sign textures).
+- [ ] Add a sidewalk concrete texture and street asphalt texture with a center-line decal (generate seamless textures).
+- [ ] Add a sky: `ProceduralSkyMaterial` or a generated skybox, plus a sun with soft shadows (currently a bare `DirectionalLight3D` + flat ambient).
+- [ ] Add simple props for depth: bollards, a trash can, a street lamp, a planter near the entrance (generate or model low-poly props).
+- [ ] Add a night/evening lighting pass: dim ambient, warm street-lamp point lights, and a visible flashlight cone (ties into the existing `G` flashlight toggle).
+
+### NPCs
+
+- [ ] Replace capsule bodies with a simple humanoid rig (head/torso/limbs) or a low-poly character mesh, keeping the archetype color coding as a fallback.
+- [ ] Add per-archetype visual identity: distinct silhouettes or accessories (e.g. camera for influencers, delivery box, performer prop) instead of color-only.
+- [ ] Add a simple walk/idle animation (procedural bob or imported animation) so NPCs don't glide.
+- [ ] Add a facing/attention cue: NPC head turns toward the guard when `perceive_guard` reports `aware`/`near`.
+
+### UI and feedback
+
+- [ ] Replace text-only inspection with visual artifact cards: wristband/ID/ticket images showing color, pattern, date, and event marking (generate card art).
+- [ ] Add HUD icons for the tone picker, wand, flashlight, and door-lock states (generate small icons).
+- [ ] Add a subtle screen-space vignette or color grade per escalation level to reinforce the existing color-coded escalation label.
+- [ ] Add a body-camera frame overlay (corner timestamp + REC indicator) to sell the evidence/recording fantasy.
+
+### Performance and pipeline
+
+- [ ] Set up an `assets/` import convention (textures, materials, meshes) and document it in `README.md`.
+- [ ] Profile the crowd: ensure textured materials and props don't hurt the target frame rate around a busy entrance.
+- [ ] Add LOD or culling for distant NPCs/props if the crowd grows.
