   Every visual value here resolves to a token from tokens.css (var(--…)).
   No raw hex, no raw shadow, no raw easing curve. Two families only:
   Crimson Pro (display, reading) and Inter (labels, nav, buttons, chips) —
   never inverted, per design-system.md §3.1.

   Site-only dimensions (the nav height, the display type steps, z-index
   layers for this page's own fixed chrome) are declared as local custom
   properties at the top of this file. They are not part of tokens.css
   because nothing in the app depends on them — design-system.md §3.9's own
   rule: a dimension only one surface depends on stays inline, not tokenised.
