/* ---------------------------------------------------------------
   Intelligent colour adapt — requires CSS relative colour support
   (Chrome 119+, Firefox 128+, Safari 16.4+).
   Falls back gracefully to the white-backed colour-mix approach.

   Technique: mix the icon colour with a greyscale tone derived by
   inverting the lightness of currentColor.
     • white text (l≈1) → inverted l≈0 → mix in near-black → circle
       gets darker/punchier → white icon stays readable.
     • dark text (l≈0.2) → inverted l≈0.8 → mix in light grey → circle
       gets softer/lighter → dark icon stays readable.
   Active / current-page state uses a higher icon-colour weight (82 vs
   60 %) so it reads as more vibrant than the resting state.

   MOBILE ONLY — desktop uses the configured icon background color.
