/* Sæga: what every page shares. The design tokens, the skip link, the header, the
   footer and the buttons. Linked first on every page, so a page's own <style> (or
   styles.css on / and /en) builds on it and can override a token where it has to.

   The header and footer markup is written into each page by scripts/chrome.py; change
   it there and re-run, never by hand in one page. assets/site.js runs them.

   Contrast (WCAG AA, 4.5:1 for text): --text-dim is the faintest text colour and is
   chosen against the darkest background it sits on. Light #6B6B6B: 5.10 on --bg,
   4.66 on --bg-subtle, 4.69 on --bg-cool, 4.81 on --bg-footer, 4.56 on #F0EDE8.
   Dark #888888: 5.33 on --bg, 4.70 on --bg-subtle, 4.91 on --bg-card, 5.03 on --bg-cool.
   Text on the brand colour uses --brand-ink: 4.91 light, 5.96 dark. */
