/* ==========================================================================
   hexide.io
   Zero-build. No framework, no fonts to fetch, no JS required to read a word.

   Every colour below is sampled from the product's own theme files:
   Themes/Classic.axaml, Themes/Packs/Dark.json, Icons/AppIcon/hexide-logo.svg.
   Nothing here is a stock palette.

   Contrast: every text/background pair in both themes clears WCAG AA (4.5:1),
   and every focus indicator clears 3:1 against all four surfaces it can land
   on. Graphic tokens (--run/--brk/--stop) are kept for marks only; text uses
   the -text twins, because the graphic values do not clear AA as type.
