/* Krumbly — the public site (S-067).
 *
 * The tokens below are LIFTED VERBATIM from src/app.css, which took them from
 * docs/design/Huishouden - app.dc.html. They are not a second palette and must
 * not drift into one: the site's whole job is to look like the app someone is
 * about to open. When a token changes there, change it here.
 *
 * Every value carries its measured contrast from the app's gate
 * (scripts/check-contrast.mjs, 45/45 pairs). Because the pairings used here are
 * the same pairings that gate checks — ink on paper, muted on paper, accent on
 * paper, paper on ink — the ratios are inherited rather than re-derived. Do not
 * invent a new pairing without measuring it.
 *
 * Fonts are self-hosted in ./fonts, copied from static/fonts. NOT Google's CDN:
 * the no-cloud-services rule in claude.md, and a privacy-forward product that
 * leaked every visitor's IP to a third party on page load would be arguing
 * against itself.
