/* SureCite landing page — draft styles, round 4 (redesign, 28 Sep 2026).

   Direction: "the register". A calm, institutional page set like a well-made
   annual report or statute book: a text serif for headings (Source Serif 4, with
   optical sizing), a sober public-sector sans for everything else (Public Sans),
   cool neutral paper, ink-black primary actions, and one blue used only for
   what is cited or linked. No mono labels, no uppercase, no card grid: structure
   comes from a 12-column grid and hairline rules.

   Tokens are three layers (design-system skill): primitives -> semantic roles ->
   component values. Components use semantic roles only.

   Alignment rules used everywhere:
   - one control height (--control-h, 44px) for every button, field and choice;
   - repeated items (routes, steps, rows) share one structure, so their titles,
     bodies and outcomes sit on the same lines; the three routes use subgrid;
   - nothing is sticky except the site header, and every anchor target clears it
     (scroll-margin-top), so focus is never hidden behind it (WCAG 2.4.11). */
