   the lapis-900/950 navy and stay as-is — they're deliberately the "richer"
   accent tier. Everything else (page background, cards, chips, links) gets a
   neutral dark surface here so the navy sections keep standing out.
   Applies automatically via prefers-color-scheme, or explicitly once the
   visitor picks a theme with the toggle (data-theme, saved to localStorage). */
