   design tokens (Restrained: dark ground, one Committed accent).
   rules respected per impeccable craft-floor:
   - no gradient text. no nested cards. no border-left deko.
   - tight groups, generous separation, more space above headings than below.
   - one authored motion. exponential ease-out. reduced-motion path.
   - browser surfaces themed (selection / scrollbar / focus ring / caret).
