Add the Axiom Relay straight-wall group (10 models) and a loose-run axiom-wall-kit

[reposlayer]

What this is

Ten of the twenty-four briefs under docs/assets/reusable/architecture/walls/ have no model source. This adds ten of them: the three run lengths, the four opening and service variants, an obtuse turn, a faceted arc, and a cast boundary wall.

The approach

Unlike the doors and windows groups, the wall system already exists — buildWallSection in axiom-modular-kit is the canonical Axiom wall author, and it is what the prefab shells are cut from. So nine of these ten modules are that function called with a length and at most one opening. They inherit the kit's thickness, datum heights, cassette rhythm, skirt, and stepped opening frames, which means a level builder can swap wall-with-door for a solid bay and the elevation still lines up.

The new assets/prototypes/axiom-wall-kit/ support item therefore owns almost nothing. It adds only what a loose run needs and a shell does not:

• a footing, because inside a shell the wall starts at the interior floor datum and a loose run would otherwise begin 440 mm in the air;
• end returns, because a shell hides its wall ends inside corners and a cut run shows its cassette layers in section;
• a coping;
• the shared capture rig, which reuses the modular kit's existing lighting values exactly — a wall photographed under its own lights cannot be compared to the shell it is meant to join.

Modules

Module	Notes
wall-2-m	The half-bay run: the offset between a 4 m module and a corner
wall-4-m	One full structural bay; the group's reference length
wall-8-m	Two bays as one section — butting two 4 m modules leaves two end returns back to back mid-wall, and a seam every 4 m reads as fencing
wall-with-door	The kit's 1.56 m door bay, with the shared stepped frame and reveal
wall-with-window	The kit's 1.9 m window on the shared 1.32 m sill datum
wall-with-vent	Louvre bank cut as a real aperture, so the reveal runs behind the blades
wall-with-inset-panel	A 120 mm service niche with a drilled backboard — a recess, not an opening
angled-wall	Two 2 m runs at 135°, sharing a vertex post
curved-wall	Eight chords on a 6 m radius; chord length derived from radius and facet count
low-concrete-wall	Cast in bays — not the cassette system, see below

The one deliberate departure

low-concrete-wall does not use buildWallSection. The kit wall is a framed composite panel system — shop-made cassettes clipped into a structural frame. A boundary wall is cast concrete: poured in bays against formwork, with a construction joint per bay, a formwork arris, and a splayed foundation. Building it from cassettes would give a 1.1 m tall version of a building facade standing in a car park. The two share the grid, the palette, and the joint pitch; they do not share a construction. Flagging it explicitly in case you'd rather it were forced into the cassette system for consistency.

Verification

• Every module was iterated against its brief with bun run vibe:model preview.
• bun run typecheck, bun run build, and bun test (49 pass, 0 fail) all pass.
• bun run build:registries adds 10 models and 1 support item to the registry — 190 items from 184 models against the current main. Stated as a delta rather than a fixed pair, because the absolute count moves every time one of these batches lands.

Note for review

This is the third of three architecture batches cut independently from main (doors, windows, walls). All three touch the one buildSupportItem list in registries/scifi-kit/src/build.ts, so whichever land after the first will want a trivial merge on that list.

Pull request overview

Adds the new Axiom Relay straight-wall module family by introducing an axiom-wall-kit support prototype (shared wall authoring + capture rig + loose-run-only parts) and a set of wall modules built mostly via the existing buildWallSection author in axiom-modular-kit.

Changes:

• Register the new axiom-wall-kit support item in the scifi-kit build pipeline.
• Add the straight-wall module set (run lengths + door/window/vent/inset variants + angled, curved, and low concrete boundary wall).
• Introduce axiom-wall-kit shared helpers for loose-run footing/end returns/coping plus shared preview rig and wall model wrapper.

Conflict with main after #6 landed is resolved — this branch has main merged in and reports MERGEABLE / CLEAN. It was the one-line buildSupportItem list in registries/scifi-kit/src/build.ts, resolved by keeping both support items rather than choosing one. Verified after merging: typecheck clean, bun test 49/0, build:registries succeeds.

Full explanation and a note on merge order in #5.

Updated: build.ts now discovers support kits from the prototypes directory instead of listing them by hand, so batches no longer edit a shared line and these PRs can be merged in any order without conflicts. Verified by merging all four into main back to back — clean each time, typecheck clean, 49/0 tests, 223 items / 214 models combined.

Details in #5.

Same deterministic rig for every model in the wave — that is what a contact sheet is for, since the defect that matters at pack scale is whether the props read as one catalogue rather than as individually plausible objects.

Images live on the previews branch of the fork (images only, never merged), so nothing here touches this PR's diff.
