+5. **THE VERNACULAR KIT (filed 2026-07-18, John's idea, source corrected) — buildings that
+   feel real.** The town's massing is same-y boxes; the fix is **15–20 parametric Aussie
+   vernacular archetypes** (Queenslander, Federation cottage, terrace row, weatherboard
+   shopfront + verandah, deco corner pub, brick milk bar, fibro shack, tin warehouse…) with
+   seeded knobs — width, storeys, verandah depth, roof pitch, parapet, tint, and the wear
+   noise from item #3 above. **Source ruling: NOT Google Maps 3D** (licence-fatal — the one
+   thing the provenance spine must never touch — and photogrammetry mush at house scale
+   anyway). Instead: (a) **OSM/Overture building footprints + heights** for the real towns —
+   ODbL, the licence and pipeline we already ship, one more fetch class under the standing
+   authorization; (b) the kit designed from Street View *reference* (looking is not
+   extracting) and built parametrically on B's existing instanced-attribute machinery, which
+   already varies tint/hours per instance. Real footprints place real shapes on real streets;
+   the kit + knobs cover everything unfootprinted. Pairs with terrain as the two halves of a
+   future "the streetscape gets real" epoch — but unlike terrain, the kit is INCREMENTAL
+   (archetype by archetype, budget-measured, classic fenced), so it could also drip in as
+   B/E polish rounds. Goldens untouched either way (plan hashes don't see meshes); budgets
+   re-measured per archetype.
