Add body-camera timeline to the shift review

- New src/game/ui/event_timeline.gd flattens every recorded incident event
  (ADR-0005) into one time-ordered list and shows time, person, and a one-line
  summary. Step with Left/Right or the buttons; Esc returns to the review. No live
  3D replay in this first version.
- Shift review gains a "Body camera timeline" button that hands the review to the
  timeline; the review dim is hidden while it is open (stacked overlays made the
  screen nearly black) and restored on close.
- ShiftCoordinator records started_at_ms so the review can stamp events as mm:ss.
- 8 new string keys for the timeline UI and the review button.

Tests/docs
- Headless suite 113 -> 120 (test_event_timeline.gd), new smoke_timeline.gd that
  opens the timeline from the review, steps through every event, and closes back.
- README, TODO section moved to DONE, MEMORY notes. Version 0.2.6.

   Blocking also calls `_station_between()` to physically place the guard 0.9 m from the NPC toward
   the entrance. `_request_reason()` logs the NPC's seeded `dialogue_lines` pick.
+- **NPC navigation was dead (fixed 2026-10-31):** avatars never moved in the live game, for three
+  stacked reasons. (1) `agent.target_position` was re-assigned every physics frame, which
+  invalidates the path so `get_next_path_position()` keeps returning the current point — only set
+  it when the target changes. (2) Nav path points sit on the navmesh plane (y=0) while bodies stand
+  at y≈0.5, so a 3D "are we there" test always looked 0.5 m away and the horizontal direction was
+  zero — compare horizontally. (3) `path[0]` is the old start point, so picking any point "far
+  enough away" can pick the point behind you and oscillate — pick the first point that is
+  **closer to the goal** than the current position. `_nav_try_frames`/`_move_direct` fallback is
+  still there.
+- **Crowd reactions listen on the EventBus:** `CrowdSystem.apply_event()` emits
+  `event_bus.crowd_changed`; its own `changed` signal is never emitted. `GameManager._connect_crowd()`
+  therefore connects to `coordinator.event_bus.crowd_changed` (reconnect after every
+  `coordinator.setup()`, which recreates both crowd and event bus).
+- **Crowd presentation:** `NpcAvatar.start_rubberneck(at)` (idle bystanders away from the door stop
+  and face the incident for 12 s) and `start_flee(from)` (panic: walk away at 2.4 m/s, then free
+  themselves). Someone `awaiting_interaction` within 3 m of the door is "engaged" and does not
+  rubberneck. Use `position` (not `global_position`) for that distance check so it also works in
+  headless tests outside the tree.
+- **Perf:** a busy 16-NPC entrance measured ~1.2 ms/frame (824 fps with vsync off, 800 samples),
+  so LOD/culling is not warranted at `MAX_LIVE_NPCS = 16`. Re-measure before raising the cap.
 - **Incident recording was dead:** `IncidentRecorder.start_incident()` was never called, so every
   `add_event`/`add_access_evidence` silently no-opped and the review always showed 0 incidents.
   `_begin_incident()` now starts one per focused NPC (`has_open_incident()` guard), verbs call
   `_ensure_incident()`, and `ShiftCoordinator._finish_shift()` closes leftovers as `unresolved`
   before building the review.
+- **Body-camera timeline (2026-10-31):** `src/game/ui/event_timeline.gd` flattens
+  `review.incidents.incidents[].events` into one time-ordered list (`flatten`), formats each row
+  with `describe`, and steps with Left/Right or the buttons. `ShiftCoordinator.started_at_ms`
+  gives the review an absolute start for mm:ss stamps. `GameManager._open_timeline` hides the
+  review dim (two stacked overlays made the screen nearly black) and `_timeline_from_review`
+  restores it on close. Smoke: `src/test/smoke_timeline.gd`.
+- **Radio dispatch was dead after the first shift:** `coordinator.setup()` builds a new
+  `RadioSystem`, so the `responder_arrived` connection made in `_ready` was lost on every venue
+  switch/restart (responders never resolved anything). `_connect_radio()` now re-wires it next to
+  `_connect_crowd()` after every setup. Same class of bug as the crowd signal.
+- **Emergency aftermath:** `ShiftCoordinator.responder_outcomes` / `investigations` feed the review.
+  `evacuation` (emergency call, low danger, no weapon) locks the door, makes every NPC flee, marks
+  them `leave_requested`, and applies a `security_failure` hit. An emergency placed while
+  `current_npc_truth` has no weapon and `danger_level <= 1` appends an investigation note, records
+  `investigation_opened`, and applies `false_report` -6.
+- **Skyline backdrop (2026-10-31):** `PlaneMesh` defaults to a **horizontal** XZ plane — set
+  `mesh.orientation = PlaneMesh.FACE_Z` or the "backdrop" renders as a band overhead. The skyline
+  is now a ring of four 400x60 planes at 200 m (center y=30, so building bases meet the ground),
+  `TEXTURE_FILTER` default, `TRANSPARENCY_ALPHA_SCISSOR` with threshold **0.5** (0.3 left faint

 The audit classifies measurable fit issues as `good` or `bad` based on role-specific dimensions, aspect ratio, alpha requirements, and tile-edge continuity. It lists perspective/projection as a visual review item because image semantics cannot be judged reliably by these deterministic checks.
 
+### Screen design references
+
+Screen mockups and screenshot comparison use `tools/screen_designs.py`. It turns the
+screen descriptions in `docs/` (README captions, ADRs 0007–0010, `PLAN.md`, and
+`architecture.md`) into reference images under `docs/screens/designs/`, then uses
+those images as the expected state to check the game's captures.
+
+Each screen is tagged `scene` (a realistic first-person 3D world view) or `ui`
+(an in-game panel overlaid on a softened scene), and the generator appends a
+shared art-direction suffix so the frames read as one coherent game. Requests use
+a 3:2 landscape source and crop to the 16:9 capture dimensions.
+
+```bash
+# Deterministic wireframes (offline, no API key)
+python3 tools/screen_designs.py generate --draft
+
+# Realistic 3D scenes and in-game screen designs via OpenRouter
+# (requires OPENROUTER_API_KEY)
+python3 tools/screen_designs.py generate
+
+# Compare docs/screenshots/*.png against the designs
+python3 tools/screen_designs.py compare
+python3 tools/screen_designs.py compare --json
+```
+
+`compare` flags gross drift: wrong aspect ratio, undersized frame, near-blank
+frame, and large layout/palette/detail distance. It is a regression gate, not a
+semantic judge — pixel and perceptual metrics cannot decide whether a frame's
+composition is *right*, so a vision-model pass is the documented follow-up (see
+`TODO.md`). Regenerate the designs after changing screen layout, then re-run
+`compare` after regenerating the game screenshots with

+"""Generate screen-design reference images for Step Line and compare captures.
+
+This tool turns the screen descriptions that already live in `docs/`
+(README screenshot captions, ADRs 0007-0010, PLAN.md, architecture.md, and the
+HUD strings in `content/strings.en.json`) into reference "design" images, then
+uses those images as the expected state to check the game's captured
+screenshots against.
+
+Two commands:
+
+  generate   write one reference image per screen to docs/screens/designs/.
+             Two modes:
+               --ai     realistic 3D game scenes and in-game screen designs via
+                        the OpenRouter image API (default; requires
+                        OPENROUTER_API_KEY, same as tools/asset_pipeline.py).
+               --draft  deterministic wireframe sketches drawn with Pillow
+                        (no network or API key; good for CI and layout checks).
+
+  compare    compare docs/screenshots/*.png against the reference designs and
+             flag gross drift. Semantic composition is judged with coarse,
+             Pillow-only signals (aspect ratio, frame size, blank-frame
+             contrast, grayscale MAE, colour-histogram distance, edge density).
+             These catch "wrong screen / blank frame / wrong time of day"
+             regressions; they are NOT a pixel-exact or semantic match. A
+             vision-model pass is the documented next step (see PLAN.md).
