/* Edapt public site: the shared chrome and the inner pages, drawn as an
   exercise book (42-PLAN.md section 18, rebuilt 10 October 2026).

   Loads after book.css, whose tokens every rule here reads: --paper, --card,
   --rule, --margin, --ink, --ink-2, --ink-3, --sky, --sky-deep, --yellow,
   --mint, --red, --font-body, --font-note, --line (32px), --shadow, --radius.
   Everything on the paper is sized in multiples of --line so text lands on
   the rules. A card has a solid background, so the rules stop under it and
   its inner rhythm is free. The home page loads home.css after this file. */
