   Contrast safety net for tinted indigo backgrounds
   ============================================================
   Some templates use `bg-primary bg-opacity-10` (or `bg-primary-subtle`)
   as a soft circular badge with a `text-primary` icon inside. With our
   muted indigo (`#3949ab`), the 10% tint is darker than Bootstrap's
   default light-blue, so the same-color icon disappears.

   These rules force any tinted indigo container to use a near-white
   tint and a saturated-but-readable icon, keeping the design subtle
   while restoring contrast. */
