/* ── Custom (generic) skin: stepper follows the skin palette ───────────────
   The base active/completed colours above are hardcoded (blue + green) with no
   admin control. On the Custom skin they now derive from the skin's own tokens,
   so a merchant changes them in Appearance › Styles → "Accent" (completed +
   progress line) and "Text (Ink)" (active step). Layout stays the shared base
   stepper. Scoped at (0,3,0) to beat the base (0,2,0); tokens carry a fallback
   to the original colours in case the generic token layer is not loaded. */

   "Modern Skin Colors" apply). Fallbacks are Modern's own brand defaults —
   NOT the base blue/green — so even steps that don't load the RB token layer
