Wiring (F owns index.html + interior_mode.js):
• Interior presence (C->D->F seam): occupancyOf closure -> interior_mode spawns browser rigs at
C's room.browsePoints (one per patronage occupant, cap 3); freed by exit()'s keepers.disposeAll.
Door points now carry shopId for D's occupancy truth.
• Tram (Lane B, ?tram=1): createTram + update in loop (2 draws, non-blocking).
• Buy-anywhere (Lane C C2): E aimed at a book-spine/toy-box buyMesh buys over the same wallet
(collapseBuyItem + toast); preload book+toy packs too. Records keep the dig.
Harness: graduated buy-v0 / patronage / book-toy stock warn->STRICT (katoomba golden already
strict). New warn smokes: interior presence (browsers==min(occ,3), dispose clean), shelf-buy
(book spine bought, cash drops), tram (present). Book-stock check now counts isStock OR buyMesh
(C2 tags book spines buyMesh, not isStock). flags_check GREEN 0/0; qa.sh --strict GREEN 5/5.
