Cursor fluid — moving the pointer through a full-bleed dark field sheds a von Karman vortex street of alternating-sign vortices that drift downstream and decay, revealed by ~600 velocity-aligned tracer streaks; clicking drops a counter-rotating vortex pair that stirs the field for exactly 3 seconds.

Use when a full-bleed decorative fluid backdrop with no text and no controls of its own, where the cursor sheds a vortex street that drifts and decays behind whatever the caller overlays; pick hero-dipole-field or hero-gravity-well instead when the headline itself is the subject of the effect, or hero-particles-webgl when true GPU depth is worth three npm dependencies.
