   pages.css — hand-written page styles for the PUBLIC site (layouts/public).
   Loaded globally, so it is browser-cached and shared across pages.

   Consumes the design tokens defined in pivot.css (--navy, --paper, --accent,
   --font-display, ...). Written by hand rather than as Tailwind utilities so
   changes don't require re-running the Tailwind build that produces pivot.css.
