   property a `transition: color` can't ease, so switching it directly
   would snap back the instant the pointer leaves instead of fading out.

   directly. No two-layer opacity-crossfade trick needed here unlike the
   label text: the icon is already invisible at rest (opacity: 0 above) and

   toggle of background-clip to smooth over — it's gradient-clipped the
