/* OpenSet marketing site — shared styles.
   Palette/type/border language pulled directly from lib/themes.js (the same
   brand system the app uses), not reinvented for the website. Firm 2px
   borders instead of shadows, uppercase bold display type, tabular numbers,
   system font stack — all deliberate app-side choices, kept consistent here. */
