HUMAN-SCALE CALIBRATION (size truth for everything built): derive every
structure's true dimensions from the human-scale FIXED elements visible
on it — a door is about 2m tall, a window about 1–1.5m wide, one storey
about 2.5–3m, a railing about 1.1m. A hut or rooftop room with a single
window is barely one small room — never inflate a small structure into
a building-sized mass, and never shrink a large one. Every part of the
structure and its surroundings must agree with these anchors at the
same time.
