   Look and feel (core#118): a text face for the prose, and a palette derived
   from one colour. Source Serif 4 (SIL OFL, src/fonts/OFL.txt) is self-hosted
   - no font CDN, nothing that tracks readers - in two subsets: Latin (en, es,
   pt) and Latin Extended, which a page downloads only if it uses one of its
   characters. Navigation, labels, tables and figures stay in the system
   face; only running prose takes the serif, with old-style figures.
   Each site declares --accent; the dark shade and the soft tint derive from
   it in OKLCH, calibrated against the 23 hand-tuned pairs (mean deltaE 0.02
   and 0.009). A browser without relative colour syntax keeps the site's own
   declared values.
