// SHUFFLE H — horizontal strips shuffle sideways at a per-strip speed
|
|
// drawn fresh from a hash every beat; a rhythmic slice-and-scramble.
|
|
// The speed is quantised on floor(beat), never a running accumulator:
|
|
// each strip's speed is fixed for the whole beat and the shift resets
|
|
// to zero at the top of the next one.
