   hover. No serif display axes. No font-variation-settings.

   Shared primitives (.eyebrow, .numeral-marker, .pullquote, .callout,
   .btn--*, .card, .chip, .page-hero) live in components.css and are
   referenced, not redefined.

   honors. The Flat-at-Rest, Hover-via-Shadow-Not-Translation, No-Glow,
   Microsoft-600, No-Tracking, One-Voice, and 65ch rules all apply.
