/**
 * Hero "how it works" animation: add the card, show it at the till, enjoy the perks.
 * hero-demo.js steps data-scene through 1 → 2 → 3 → 4 (leave) → 0 (reset) and loops.
 * It also "boils" the scene like stop motion: the paper and step 3 object outlines swap between
 * slightly redrawn versions, and each piece is re-placed by under a pixel (--jx, --jy, --jr).
 * Both are plain geometry, so every browser draws them the same way.
 * Every size inside the stage is in em, so the whole piece scales from one font-size.
