/*
 * The site's one stylesheet — the Claude Design board's "Keel Website" frame in the Counter
 * system (M15.18, 1 Oct 2026), built as static pages. Every page links it; nothing is
 * styled inline.
 *
 * The token NAMES are the design system's (`--bg`, `--ink`, `--accent`, `--brand`…), so
 * the board and this file read the same. The VALUES are copied from `src/design/web.ts`,
 * because these static pages have no build step that could import them. `page.test.ts`
 * fails if a variable here differs from it, and `contrast.test.ts` computes every pair of
 * them that puts a word on a ground.
 *
 * Light only, as the app is. The two forest bands are `--brand`, not a dark scheme. No
 * gradient, blur or shadow anywhere: Counter draws none.
 */

   Outfit for display — titles, numerals, labels and the wordmark; IBM Plex Sans for every
   sentence; IBM Plex Mono for figures in the working. Outfit ships in the two weights
   Counter sets, 600 and 700, the same two the app renders.

   SELF-HOSTED, as WOFF2 cut to the characters the site sets (`scripts/web-fonts.mjs`, from
   the same node_modules faces the app renders); the build renames each by its hash. A link to
   fonts.googleapis.com would send every visitor's IP to Google from a site whose
   whole argument is that Keel does not do that. */
