// TIME SLICE — the frame is sliced into scanline bands and each band runs
// on its own delay: the top of the picture is already on the new frame
// while the bottom is still holding the last one, and the boundary rakes
// down the frame once a beat.
//
// Pattern taught here: ONE STORED FRAME IS ENOUGH. A true per-line delay
// would want a whole ring of frames; the `hold` stage keeps exactly one and
// indexes the CHOICE by position — band n releases to live when the beat
// phase passes n/bands. The result reads as a per-line delay, costs one
// texture, and is bounded by construction (the phase is a 0..1 saw, the
// index a function of the band number — nothing accumulates).
