   Chill — cool, crisp air for air-conditioning companies.
   Matte appliance panels, soft-touch remote keys, LCD seven-segment readouts,
   vent louvres and frost. Colours, spacing, radii, shadows, durations and
   easings come from tokens.css; this file adds construction and motion.
   Rules: movement is transform/opacity only; entrances fill BACKWARDS;
   box-shadow changes only on one element's own state; one looping effect
   (the airflow drift) per page, pausable.
