/* eitri design system: tokens, type, and the few components every page shares.
   Dark engineering theme by default; [data-theme="light"] on <html> switches to light.
   One accent (signal orange) used sparingly: primary actions, the active tool, focus, the wordmark.
   Status colours are separate from it: green = check passes, red = check fails, amber = warning.
   Fonts and icons are bundled (assets/fonts, assets/icons.svg): nothing is fetched from the internet. */
