/* ---------- The spinning coin ---------- */
/* NOTE: this used to be a "real" 3D flip (perspective + preserve-3d +
   backface-visibility + rotateY). That's the technique most tutorials use,
   but a lot of Android/mobile GPUs either don't support compositing nested
   3D layers properly or silently fall back to a flattened 2D approximation
   for them — and that fallback is exactly what reads as "sliding sideways"
   instead of spinning in place. Repositioning `perspective` wasn't enough
   because the underlying problem is the 3D transform itself being
   unreliable on these devices, not where perspective was anchored.
   Switching to a 2D scaleX "fake flip" (below) sidesteps the whole
   category of bug: it only ever asks the browser for a 2D transform, which
   every device handles identically and predictably, so there's no 3D
   compositing path left to fall back out of. */
