   qft-variations-wild.mjs — sketch 09 · running wild.

   New mechanics this sketch:
     - VORTEX perturbations (swirling rotation around a centre)
     - STANDING WAVES (global plane-wave modulation; Chladni)
     - CURVED Feynman links (bezier-curved propagators)

   Plus everything earlier: wavepackets, ripples, dense cubic,
   per-field weights, mid-tone substrates.
