/* ============================================================
   Aspect V3 home - pair builder (markup build.mjs §pair, behaviour v3.js "Pair builder").
   A white tile: copy + one-tap popular pairs on the left, a navy stage on the right where the two
   real vials stand on lit plinths, joined by a pulsing "+". The vial of equal or lesser value is
   stamped $0 (mint plinth). A full-width total bar sits under the vials so nothing ever clips.
   MOTION: on enter vials rise (120ms apart), the orb pops, the beam draws, the $0 tag stamps;
   on change the vial drops out and the new one rises, prices roll, the $0 tag re-stamps where it
   lands; orb ring pulses gently while in view. Reduced motion: static.
