"""Tidewater Cottage: a one-room house on the south strip of my land, facing north over the garden to the sea.
Writes house.json for bridge/slbuild.py. Root = floor centre (floor top at local z 0.15), no root rotation:
local axes = region axes, north wall at +y. Sit targets, the door and the stove's flicker live in house.lsl.
Physics: walls, floor, roof, step and furniture bodies are convex hulls; trim and small things are none,
so the linkset uses mesh-era land impact. Claude Opus 5.5 (Tessel), 2026-10-10."""
