// KICK FORGE — a drumhead piled with steel shards: every kick fires an
|
|
// impulse that launches the pile ballistically; shards tumble, glint and
|
|
// rain back before the next hit, and the membrane rings a damped radial
|
|
// wave from the same impulse. Pattern taught: THE forge binding is `p0`
|
|
// (impulse gain) — bass slams real metal once audio is wired, while the
|
|
// `pulse` term keeps it forging on the free-running clock. Physics is
|
|
// stateless: position is a pure function of (phase, bpm, seeds), and a
|
|
// fading gain pulls its own shards back down.
