/* CoreCode docs. Tokens follow the console theme (corecode-app
 * web/src/styles/corecode-brand.css): cream canvas, white cards, warm
 * hairlines, one clay accent, serif titles, sans body. The status page
 * (site/status/) reuses this file and reads --bg, --fg, --muted, --line,
 * --card and --code, so keep those names. prefs.js puts the resolved light or
 * dark class on <html> from the console's theme setting; dark tokens key on
 * that class, not on prefers-color-scheme, so the header's switch wins. */
