   Light defaults live in :root. The dark overrides apply only when the HOST sets

   does, so it always resolves the light values. Defined here (not in Flex's
   AgCF.css) because ClickForms doesn't load AgCF.css. Never hardcode a color in the
   rules below — reference a token. Semantic hues stay; only lightness flips for dark. */
