   One file for every page: fonts, tokens, base, layout, type, buttons,
   data tags, the relayfi-style bar + mega sheet + phone sheet, films,
   footer, closing band, and the motion utilities (merged, per TECH-BASE).
   Every rule describes a FINAL state. Start states for motion live behind
   `.motion` (set in <head> only when JS runs and reduced motion is off).
