   6. Colors

   Per Sue, 2026-09-21 ("full enchilada... keep going" on Customizer color
   control): every class below that maps 1:1 to one of the 16 --uis-* CSS
   custom properties (see style.css :root, and class-ui-customizer.php's
   Interactive Color Palette section) now reads that variable instead of a
   hardcoded hex value. No template markup had to change (same principle
   as this file's original purpose per the header comment above) -- every
   .bg-white, .text-slate-600, .bg-blue-600, etc. already in header.php,
   footer.php, templates/*.php, archive-*.php, single-*.php becomes
   Customizer-controllable automatically, on both this site and the forum
   (class-uis-forum-branding-sync.php syncs the same 16 variables).

   Deliberately NOT variable-driven, left as literal hex/rgba (documented
   limitation, not an oversight):
   - Opacity-suffixed variants (bg-white/90, bg-slate-900/80, etc.) --
     these are translucency/glass effects layered on a base color, not a
     standalone brand color choice; tying them to a var without a
     color-mix()-based approach would need one new variable per opacity
     step for no real customization benefit.
   - Light color TINTS used as badge backgrounds (bg-blue-50, bg-amber-100)
     paired with their own darker text (text-amber-800, etc.) -- these are
     fixed light/dark pairs for badge contrast, not swapped independently.
   - hover:* color states (Section 9 below) -- still hardcode a hover
     shade of the ORIGINAL default brand color. If brand_blue is changed
     in the Customizer, buttons using it pick up the new color immediately
     but their :hover state still darkens toward the old default blue
     rather than a darker shade of the new color. A correct fix needs
     either a dedicated "hover" variant of each brand color or a
     filter: brightness()-based hover instead of a color swap -- flagged
     as a follow-up, not attempted here to avoid changing interactive
     behavior on every button in the theme in the same pass as color
     values.
   - Single-use decorative icon colors with no brand meaning (text-red-500
     heart icon, text-green-500 checkmark, text-orange-500 RSS icon,
     text-blue-400 lock icon, border-amber-300/400 badge borders).
   - text-white -- used for text ON dark/colored surfaces for contrast,
     not as a standalone color choice; pairs contextually with whatever
     dark background surrounds it.
