/* ==========================================================================
   Admin-selected colour theme (Settings -> Customizations -> "Look and
   feel"). "teal" is the block above — the shipped HITT palette, no override
   needed, so an instance that never touches this looks exactly as before.
   Each other preset restates the two brand hues (--hitt-teal / --hitt-amber
   — most of the app's CSS reads these directly, and so does the override
   block in css/projects.css for the one page still on compiled Tailwind)
   plus the handful of hover/focus tokens the base :root sets as fixed
   values rather than deriving from those hues. Dark mode needs its own
   --brand/--brand-hover per preset too — the base dark block already hard-
   codes those independent of --hitt-teal (for contrast against a dark
   background), so overriding --hitt-teal alone wouldn't reach them.
   See public/js/branding.js for how <html data-theme="…"> gets set.
