/* Project PathBuilder — shared site kit
   Palette: deep navy / warm gold / off-white / navy-charcoal.

   Two kinds of color tokens on purpose:
   - Semantic tokens (--pb-page-bg, --pb-surface, --pb-ink, ...) FLIP
     between light and dark mode — these drive normal page chrome
     (header, body text).
   - Fixed "band" tokens (--pb-band-*, --pb-footer-*) do NOT flip — the
     hero and footer are always a dark navy / near-black band with light
     text, regardless of site theme, the same way they'd look on any
     marketing page. Using the flipping tokens there was an earlier bug:
     in dark mode it made hero/footer text turn dark-on-dark and nearly
     unreadable.

   Where noted, semantic tokens are mirrored onto Jelly UI's documented
   --jelly-color-* custom properties so its components (jelly-badge,
   jelly-theme, etc.) pick up the same palette instead of their own
   defaults. Harmless if the exact property names Jelly ships differ —
   unknown custom properties are simply ignored. */
