/* ==========================================================================
   pricing.css — glassmorphic tier carousel.

   The cards are the brand's glass tiers made literal: an inactive card is
   glass-1, the focused card lifts to glass-3 with its own mood glow behind it.
   The track is a scroll-snap carousel so it works with a trackpad, a drag, the
   arrows, the dots and the keyboard without a library.
