fix(kit): cap bay count and fill the storey spread; fetch the retail reference

Kit layout, found while starting the retail pass:
- Bays were round(width / 4.96), so 6922 (65.8 m wide) got 13 bays - a window every
  4.96 m across a 37 m block. Capped at MAX_BAYS = 9, widening the module instead.
- Storeys were assumed exactly 310 cm apart, leaving ~1.6 m of bare wall under the
  cornice on a tall building. The spread is now derived from the available height
  (usable / storeys), so the top band lands inside the volume.
  Result: 6922 9x11 (was 13x11), theatre 8x6, 6806 7x3, 6800 4x3, TCL 9x5.

Retail references: fetched Art/reference/retail-neighbours/01-lee-drug-and-neighbor.jpg
(Gb321, CC BY-SA 4.0) - 6800 and its neighbour at street level, confirmed to show
shopfronts and parapets. Commons has nothing for 6822 or 6806-6820, so those two
remain blocked on reference photography; recorded in TODO.

Re-applied the kit, repackaged, screenshots re-rendered and verified 4/4, packaged
QA all PASS.

 ### Patch tasks
 
-- [ ] **Retail neighbours (6822 Budget, 6806–6820, 6800 Lee Drug) from their own references.** The 18-frame set is the El Capitan Theatre, so it cannot stand in for these façades. Fetch or shoot per-building references first, then model the shopfront line and upper storeys rather than relying on the kit alone.
+- [A] **Retail neighbours (6822 Budget, 6806–6820, 6800 Lee Drug) from their own references.** **Started 2026-11-09.** Fetched the one usable reference Commons holds for this run — `Art/reference/retail-neighbours/01-lee-drug-and-neighbor.jpg` (Gb321, CC BY-SA 4.0, 1920×953) — which shows 6800 **and** its neighbour at street level; the vision pre-check confirmed shopfronts and parapets are visible. The 18-frame theatre set cannot stand in for these façades, and Commons has nothing else for 6822 or 6806–6820, so per-building references for those two remain the blocker. **Kit layout fixed while here:** bay count was `round(width / 4.96)`, which gave 6922 thirteen bays across 65.8 m (a window every 4.96 m on a 37 m block) and left bare wall under the cornice; bays are now capped at 9 with the module widened, and the storey spread fills the available height (6922 9 × 11, 6806 7 × 3, 6800 4 × 3, theatre 8 × 6).
 - [ ] **Hero façade: fluting and the motto band as geometry.** The colonnade is plain cylinders and the motto/medallions are flat panels; both are legible in the reference photography.
 - [ ] **Blosm blockout cleaning pass.** Roofs and facades remain untextured volumes and the `setupScript` styles stay unused; with the kit carrying the elevations, this is now cleanup rather than a second façade system.
 - [ ] **Re-measure 1440p performance** with 625 kit actors and 8 generated textures in the map. `0.1.0` measured 414 fps average, so there is headroom, but it has not been re-run since.
