Character and movement pass

NPC characters
- Articulated rig (hips/knees, shoulders/elbows/hands) replaces rigid capsules;
  the walk cycle bends knees and elbows and flees with a longer stride.
- Layered outfits (jacket/vest/coat/dress), extended accessories and hand items
  (bag, umbrella, phone, camera, clipboard, cup), face details and five hair
  silhouettes, all deterministic per profile seed.
- Idle behaviour layers (phone, clipboard, crossed arms, look-around), breathing
  and weight shift; escalation raises hands or points, and noticed NPCs turn
  toward the guard.
- Reaction symbols above the head (!!, ?!, !, ?), door-queue offsets assigned by
  GameManager, three LOD tiers with hysteresis and a billboard impostor.
- smoke_npc_budget.gd: 16 avatars = 534 meshes, ~6.9 ms average (50 ms budget).

Player movement
- Separate accel/decel, step-up assist for kerbs and the entrance steps, and a
  forward-axis fix: W was inverted (get_axis(forward, back) is negative).
- Head bob, landing dip and precision-walk FOV, gated by persisted head-bob and
  invert-Y settings; precision chip and tick; surface-aware footsteps and a
  landing cue forwarded to AudioFeedback.
- Gamepad support (sticks, deadzone, face buttons, bumpers), a control legend
  that follows the active device, and named actions for the remaining keys.
- Key/button remapping in Settings, persisted as input_bindings and applied by
  InputBindings (mouse and gamepad axes are never removed).
- smoke_movement.gd (windowed): climbs the steps, checks precision speed, chip,
  footsteps and landing; new 11-precision-walk capture and catalogue entry.

Verification: headless 208/208, Python tooling 56/56, all 11 smokes pass,
compare 11 good / 0 bad, movement judge match. Version 0.5.0. Only optional
Future ideas remain in TODO.

 - **Prop pipeline (done):** audit enforces 400 tris / 600 verts, ground contact, UV range, no
   degenerate tris, one material. `capture_prop_gallery.gd` writes `10-prop-gallery.png` (3x2 studio

+- **NPC character pass (v0.5.0):** Rig is articulated (`Rig/Hip* -> Knee`, `Shoulder -> Elbow ->
+  Hand`); `outfit_for` adds layer/hair_style/hand_item; `_idle_layer` drives phone/clipboard/crossed
+  and escalation gestures; `_reaction_tag` shows `!!`, `?!`, `!`, `?`; `apply_lod` swaps to a
+  billboard impostor at 26 m (hysteresis 1.5 m); GameManager `_refresh_queue` assigns queue offsets.
+  Perf: 16 avatars = 534 meshes, ~6.9 ms headless.
+- **Player movement (v0.5.0):** **W was inverted** (`get_axis(forward, back)` is negative for W and
+  the code multiplied it directly); now `forward * -input_dir.y`. Step-up uses test_move + a raised
+  copy (0.32 m). Guard emits footstep/landed/precision_changed; GameManager forwards them to
+  AudioFeedback and the HUD. Gamepad actions are added at runtime by
+  `GuardController._ensure_gamepad_bindings`; remaps persist via `Save` `input_bindings` and are
+  applied by `InputBindings.apply` (key/button events only). Windowed `smoke_movement.gd` guards it.
+- **Scheduled TODO pass complete:** only the optional Future ideas remain (live replay, extra
+  venues, voice audio, image-to-mesh). Grounding facts: the
   NPC rig is rigid capsules with a whole-limb swing, and `guard_controller.gd` uses one `accel`
   value. Each task should get its own windowed smoke or capture where it changes feel/looks.
