/* SOLID CITY — NĀ HALE O NĀ KŪPUNA: THE ANCESTORS' HOMES (2026-10-12, by order of the King)
 * "We need to build homes for hawaiians." — homes woven into the green coastal
 * benches around THE ANCESTRAL ROADS (0,-1600), on the ancestors' own land:
 * 'ohana compounds (a main hale, a kupuna hale, a keiki hale around a shared yard),
 * plantation homes, Dickey-roof residences, traditional hale, small apartment
 * blocks at the base — following the verified historic style guide (hale →
 * plantation → Dickey → mission).
 *
 * Design sources (the King's method): three AI reference images (compound / plantation
 * home / mountainside pattern) + his real Hilo ground photos (steep roofs, A-frame gables,
 * earth-tone stucco, lawn-and-path layout, yellow path stones).
 *
 * PLACEMENT LAW (the King's word): homes sit on gentle slopes and valley floors ONLY —
 * never on ledges, ridge crests, or cliff edges. Ledges keep their natural form.
 * Every home has a driveway and a parking pad. Every home is WALK-IN: a real door
 * opening, a real little interior, walls solid, door gap passable.
 *
 * Performance: ALL static geometry is merged into a few vertex-colored batches
 * (opaque / glow / glass) — the whole mountainside is a handful of draw calls.
 * Self-contained ES module:
 *   import { createMountainHomes } from '/city/mountain-homes.js';
 *   const g = createMountainHomes({ THREE, groundAt });
 *   // g.userData: footprint [x,z,w,d,y0,y1,rot] (world), standRects, homes, update(t)
