/* Urverk — Nordic precision-mechanism. Scandinavian minimalism meets fine
   watchmaking: generous whitespace, a precise modular grid, hairline rules like
   watch-face indices, one brass accent, and one place per page where the
   mechanism comes alive. The eight palette tokens are the only hex literals in
   this file; every other colour is derived via var()/color-mix() so the palette
   guard holds. Light is the committed default; a dark theme is built from the
   same tokens under prefers-color-scheme. */

/* Self-hosted fonts — no third-party request, no render-blocking CDN, and a
   strict font-src 'self' CSP. Only the latin subset is committed (the site is
   English). Space Grotesk is the engineered display face; Inter carries body
   and UI. unicode-range copied from the Google latin @font-face blocks so glyph
   coverage is identical. */
