v0.3.0: rendering pass, generated props, selection model and Web build

Rendering and presentation
- Shared surface-material module (src/game/materials.gd) with per-surface
  roughness/metallic/uv profiles; ACES tonemapping, glow, fog and phase-driven sky
  energy. WorldBuilder rebuilt on those profiles with facade windows that light up,
  door trim/handles, curb, lane dashes, bollards, bench, bin and planter foliage.
- NPC silhouettes: per-role clothing palettes, caps/hoods/backpacks/sunglasses,
  hands and shoes, arm/leg walk swing.
- Six generated low-poly GLB props (bollards, bench, bin, planter, newspaper box,
  hydrant) built by tools/model_pipeline.py, loaded by WorldBuilder with a
  procedural fallback; ADR-0012.

Selection and movement
- Focus ranking by view angle then distance (NpcFocus.rank_indices); Tab and the
  mouse wheel cycle nearby people initially, right click clears focus with a
  re-acquire grace, HUD shows the candidate count, Shift walks at half speed.
  ADR-0011. Windowed smoke extended to cover wheel cycling and clearing.

QA tooling
- screen_designs.py catalogue grown to 19 screens (8 scene, 11 UI) plus a `list`
  subcommand; draft generation keeps existing AI references unless --force.

Web export
- New Web preset using the non-threaded Godot template (static hosting, no
  COOP/COEP). tools/build_releases.sh exports build/web and packages
  build/step-line-web-<ver>.zip; publish_release.sh uploads it with the desktop
  artifacts. test_web_export.gd covers the preset and release wiring.

Verification
- Headless suite 177 -> 181, Python tooling 53 tests, all eight smokes pass
  (including the windowed focus/wheel smoke). Web bundle serves index.html,
  index.wasm (35 MB) and index.pck (30 MB) with HTTP 200 from a static server.
- Version 0.3.0; README, PLAN, RELEASING, TODO/DONE and MEMORY updated.

+## Rendering, Models, and Selection (v0.3.0 pass)

+Decisions: [ADR-0011](docs/adr/0011-aim-free-selection-and-precision-walk.md) aim-free selection and precision walk, [ADR-0012](docs/adr/0012-surface-materials-and-generated-props.md) surface materials and generated props.
+
+The blockout look and the aim-first selection model were the two biggest gaps left by the control pass. This pass closes them without changing the game's rules.
+
+**Look.** Surfaces get real profiles instead of stock materials: brick is rough and finely tiled, concrete is rougher still, asphalt is smoother and damp-looking, glass is smooth and slightly metallic. The environment gains ACES tonemapping, soft glow, aerial fog and a mild grade, all driven by the same per-phase configuration that already moves the sun and sky. The facade gains framed windows that light up after dark, a stone base course, door trim and handles. Street furniture becomes real geometry: bollards, benches, bins, planters, newspaper boxes and a hydrant, built as `.glb` props by `tools/model_pipeline.py` with a procedural fallback. NPCs get per-role clothing palettes, small role accessories (cap, hood, backpack, sunglasses, lanyard), hands, shoes, and an arm/leg walk swing. The rule stays: the player judges people from clothes, props and behaviour, never from an archetype label.
+
+**Models.** Prop meshes are deterministic primitives, so the build works offline. An image model can supply the per-prop colour palette from a concept sheet; that is the only AI influence on geometry, and it is optional. Colours are converted from sRGB to linear before they reach glTF, because glTF factors are linear.
+
+**Selection.** The focus cone ranks heads by angle from the crosshair then distance. `Tab` and the mouse wheel cycle nearby people nearest-first and pin the choice, so aim-free play works. Right click clears focus and briefly suppresses re-acquisition. Holding `Shift` walks at half speed for close work at the door. Escape keeps its single meaning (close the top panel, otherwise pause).

 ## Design Direction
 
 The game should feel like a tense workplace simulation with occasional crisis moments. The most satisfying outcome is not overpowering an NPC; it is recognizing the situation early and resolving it calmly.
