// JUNE FIELD — a dark summer meadow of fireflies pulled into sync by the
|
|
// music. Pattern taught: the firefly engine's ONE emotional lever — blink
|
|
// phase = mix(own clock, beat phase, sync) — driven by a binding: `p0`
|
|
// ADDS to the base sync, so `env(bar)` makes the field snap together at
|
|
// every bar start and dissolve back into chaos as the bar runs out.
