/* tokensaver Site — shared styles. Nord-themed redesign (branch:
   feature/landingpage_redesign_based_on_omarchi), following the omarchy-style
   prototype at site/prototype/style-tile-omarchy.html: dark-first Nord
   ("polar night" bg, "frost" accents), JetBrains Mono for everything, hairline
   borders, sharp buttons, generous whitespace. Light mode is the Nord "snow
   storm" palette, opted into via [data-theme="light"]. */
