Two rhythms, one grid
Docs and marketing: sections at 64–128, cards at 24–32. The luxury signal is air.
Five lanes on a laptop: panels at 16, gaps at 12, rows at 8. Calm through alignment, not air.
There is no second spacing scale. "The luxury signal is air" was written for a
marketing page; an operational board that honoured it would fit three lanes on a laptop.
But a parallel compact scale would drift, so the app keeps the same 4px grid and simply
lives on its lower half, with the shared dimensions named once in tokens/app.css
(--app-pad, --app-gap, --control-h) so mixed rows
align without per-surface invention. Type does the rest: same size ramp, sans family,
--lh-ui for chrome and --lh-ui-tight inside rows — density comes
from leading and family, not from smaller text.
