/* All2One SiteChat — shared marketing + wiki stylesheet.
   Every color routes through a CSS custom property so the theme editor
   (shared/editor.html) can override any of them per dark/light mode.
   Translucent tints are derived with color-mix() from the same variables,
   so edited colors propagate everywhere. */
