/* Without relative colour syntax (Safari < 16.4, Firefox < 128) every

   the last declaration even when the engine can't use it, so the fixed
   default-violet values and the color-mix() ones need separate @supports
   blocks rather than two lines in one rule. The gradient darkens instead of
   rotating hue; accent text is mixed toward black/white until it is AA.
   shortcut: --text-on-accent stays white, so a very light custom accent
   (yellow, lime) loses contrast on these engines only. */
