/* =========================================================================
   RELY PAY — Checkout stylesheet
   Concept: the card reads like the display of a physical payment terminal —
   dim counter lighting behind it, a status LED that tells you the
   connection is live, and a progress ring around the brand mark that fills
   as you move through identify → verify → pay. No JS changes required:
   step progress is driven purely by :has() watching which panel is visible.
