/* ── Active-alert radiating animation ──────────────────────────────────────
   Two accent-matched layers emanate from the badge corner (top-right) inward:
   ::before = a soft ambient glow that "breathes", ::after = a ring "ping" that
   sweeps across the button and fades. Both are inset:0 so the corner badge
   (positioned outside the button) is never clipped. Colour follows severity;
   the cadence is slow/ambient (errors a touch quicker). The badge itself does
   not animate. No animation while clear (no accent set). Icon + badge stay
   layered above via z-index so they read crisp over the glow. */
