/* ── Redesigned USDT calculator — Direction B (floating focal element) ──────
   The calculator is the raised focal panel of the hero: it upgrades the base
   .pm-panel to the FLOATING plane (surface-raised + shadow-4 + primary glow rim
   + lit top edge) so it reads as lifted above the hero. Orange is reserved for
   ONE thing per view: the result number (the payoff). Everything else that used
   to be orange decoratively (buy-rate badge, min-amount notice) is de-accented.
