// CONFETTI SWARM — the hard-techno flock: five hundred additive neon
|
|
// gliders, and a PREDATOR dives through the swarm on every bar so the
|
|
// whole formation detonates and re-forms in four beats. Pattern taught
|
|
// here: `predator` is the flock's bar-synced scatter (CPU-side boids, no
|
|
// binding needed), `additive: 1` flips the same engine from silhouettes
|
|
// to light streaks, and pulse-driven feedback smears the scatter into
|
|
// trails.
