# A one-bedroom laneway cottage — 49 m² that reads as one program.
#
# Nothing here is positioned by hand. Every opening is pinned to a run distance along a
# named wall (`on <wall> at <pos>`), every fixture resolves against a room or a wall
# (`in <room> anchor …`, `against wall …`), and the bath/bedroom pair is laid out by
# `strip`. `site { street north }` names the two facades the plan turns on: the door
# faces the lane, the glass faces the garden.
