/* thawt.net theme (docs/ARCHITECTURE.md SS9): grayscale only, no hue
   anywhere, including the focus ring - "accent-free" per that
   requirement. Visual direction is a stark, high-contrast "elite
   intelligence platform" look: heavy tight-tracked display type, hairline
   rules instead of filled cards, sharp corners throughout, small
   wide-tracked uppercase labels for structure. Light is the default; dark
   follows the OS via prefers-color-scheme - both are full-contrast, not
   just an inverted afterthought. */
