merge: bring main (v0.1.6) into anim-body-0.2.0

Conflicts resolved by union, not by picking a side:

- AGENTS.md keeps the stronger visual-review rule (README updated with every visual
  change; a stale section is a defect).
- render_screenshots.sh keeps the absolute engine path from main and adds
  -thirdperson from this branch - both were needed and neither alone worked.
- Screenshots/README.md now lists six shots, retail and third-person both embedded;
  the known-issues tables merged, with the animation defect and unproven camera
  collision added to main's rows.
- visual_targets.json carries both expectations.
- Architecture docs: ADR-8 (realistic buildings) and ADR-9 (third-person body) both
  present and in numeric order; ADR-8 was mis-placed before the Quality Requirements
  heading in the combined document by an earlier edit, now fixed.
- Binary conflicts resolved to main's content, since the retail trim only exists
  there.

Checks: 82 tool tests, prettier clean, six embeds resolve.

-- [ ] **Model 6822 Budget, 6806–6820 and 6800 Lee Drug from their own references.** `Art/reference/retail-neighbours/` holds 6800 and its neighbour (Gb321, CC BY-SA 4.0); Commons has nothing usable for 6822 or 6806–6820, so those two need photography before they can be modelled honestly. Do not substitute the El Capitan Theatre's 18-frame set — it would misattribute the façades.
-- [ ] Review every façade change with `Tools/render_screenshots.sh --verify` before tagging.

-## 0.9.0 — Feature freeze, public beta, license and build audit (weeks 31–34)
+## 0.9.0 — Realistic buildings (weeks 31–34)
+
+Suggested blender skills: **archviz** (real-world scale, façade composition, elevation read), **references** (reference-image-match and visual-match checklists — every building is judged against its own photograph), **procedural-modeling** + **geometry-nodes** (the façades system: bay module, cornice and coping profiles, storefront types as reusable node groups), **materials** (measured albedo and roughness per surface type), **texture-workflow** (baked AO/curvature/normal, decals for painted lettering and signs), **uv-workflow** (texel density and modular UVs), **lod-pipeline** (LOD chain per building), **collision-proxy** (UCX proxies so detail geometry is not the collider), **lookdev** (screenshot comparison loop), **camera-cinematography** (reproducing each building's reference angle), **asset-optimization** + **unreal-export** (pre-export validation, `ue_metric_v1`), **qa-review** (the gate before every review shot).
+
+### Façade system
+
+- [ ] **Extend the module kit beyond one order.** Art Deco, neoclassical and streamline-moderne variants on the shared 4.96 m bay: alternate window proportions, spandrel and transom bands, and the way each order terminates at the roof.
+- [ ] **Build a profile library** for cornices, copings, string courses, sills and storefront surrounds, so a building is assembled from named profiles rather than ad-hoc boxes.
+- [ ] **Storefront types**: recessed entry, bulkhead and kickplate, mullion spacing, transom, awning/canopy brackets, and grille/shutter variants.
+- [ ] **Signage and lettering as decals.** Painted wall lettering, blade signs and fascia panels become texture and decal work with a documented projection; `0.1.6` proved that lettering built as geometry plates cannot resolve at review distance.
+- [ ] Document the system in `Art/blender/README.md` and the arc42 building block view.
+
+### Per-building models
+
+Each building needs its own reference set; where none exists the blockout stays and the item says so.
+
+- [ ] Hero façade (6840): raise to this pass's detail level — capitals and fluting, window rhythm behind the colonnade, parapet motto band and medallions.
+- [ ] Hero façade (6840), entrance: **doors at street level left and right of the central bay**, as the photographs show, and correct positioning of the central-bay elements (column bases, entrance stairs, set-back entrance, door frames, banners and signage). Nothing may stand in front of the façade that blocks it — no awning, no temporary structure. Carried over from `Screenshots/README.md`, 2026-11-09.
+- [ ] El Capitan Theatre (6838): marquee, blade sign, entrance and the theatre's own elevation from its 18-frame set.
+- [ ] 6800 Lee Drug and 6806–6820: second pass on the `0.1.6` trim. Moved here from that patch because geometry cannot close them: **wall lettering as a decal** (a plate at 0.10 m still vanishes at 40 m), a **moulded parapet profile** instead of a two-tier box, richer **corner-tower stepping**, and the portrait panels reworked as textures rather than framed plates.
+- [ ] **Photography gap — 6822 Budget** (deferred out of `0.1.6`, blocked): no photograph exists; the single-storey 6.0 × 5.5 m volume cannot be read from the neighbour shot, so it stays a bare blockout until references are acquired. Record the sources checked in `Geo/`. Also re-shoot 6806–6820 and 6800 from the south sidewalk: the only reference is one oblique with a bus across Lee Drug's shopfront and a car across 6806's.
+- [ ] 6902, 6922 and the remaining south frontage.
+- [ ] North side: TCL Chinese Theatre and Madame Tussaud's façades from their reference sets.
+- [ ] Reconcile every modelled height against `Geo/tools/block_height_report.py` and record the source per building.
+
+### Materials, UVs and performance
+
+- [ ] **Measured material library**, including the hero's stone, which currently renders pale because it is a procedural graph and a generated texture set rather than a measured surface: stucco, painted render, ashlar, brick, terrazzo, glazing, bronze and steel trim, with albedo and roughness taken from the photographs rather than guessed; one Unreal material instance per surface type.
+- [ ] **Texel-density rule** per building class, applied through modular UVs; lightmap UVs where required.
+- [ ] **LOD chain and collision proxies** per building: UCX proxies for blocking volume, detail geometry non-colliding.
+- [ ] Re-validate the 60 FPS floor at 1440p once the detail lands, and record the cost of the pass.
+
+### Release checks
+
+- [ ] Every building with a photograph has a review shot measured against it, with silhouette and proportion deltas recorded in `Screenshots/README.md`.
+- [ ] No building carries an unverified façade; blockouts without references are listed as such in `TODO.md`.
+- [ ] Every building has a collision proxy and at least one LOD.
+- [ ] No surface left on a placeholder material.
+- [ ] `THIRD_PARTY_NOTICES.md` covers every photographic reference used in this pass.
+- [ ] Performance target still met at 1440p.
