   SCREENRAY — shared stylesheet for the static content pages
   (landing pages, docs, blog). Mirrors the design tokens of the hand-tuned
   landing (public/index.html): Swiss / International Typographic, dark cut,
   coral #ff4545 on cool navy, hard grid, 4.5px radius. Archivo Expanded
   (display/body) + Martian Mono (labels/figures).

   index.html and changelog.html keep their own inline <style>; this file is
   the single source for every NEW page so they stay consistent. If a token
   below changes, mirror it into index.html's :root too.
