/* Interactive orb cue
   - `inset` controls how far outside the orb the cue sits.
   - `border` is the hard ring stroke. Keep alpha at 0 if you only want glow.
   - `box-shadow` is the visible glow/fade effect.
   - base `transform: scale(...)` controls the resting radius of the glow.
   - `hover/focus-visible` scale controls how much larger the halo gets on hover.
