Space
ZAO's base unit is the fen, after the fen of Yingzao Fashi's cai–fen module: 1 fen is 4px, and every spacing and sizing value is a multiple of it. Tailwind's spacing numbers are fen, so p-3 is 12px. Stay on these steps; anything else fails lint.

Control heights
Identical in every finish, so inputs and tabs never change size between themes. Button uses these small and large heights; its default is 34px to match its approved reference.
