/* Light beam tracking the border: an inset:-1.5px layer behind the button
   carrying a conic gradient whose start angle animates. The button's own
   background covers everything but the 1.5px overhang, so only a bright arc
   riding the edge shows. z-index -1 keeps it off the label — which is also
   why :active nudges `top` rather than `transform` (a transform would open a
   stacking context and pull the beam in front).
   Needs @property for the angle to be interpolable; without it the ring is
   simply static, which still looks deliberate. */
