| | Changing the count while the burst is idle keeps it idle: next_index_ marks "finished" by sitting at the count, so growing the count without this guard would resume a finished burst and fire hits no trigger asked for.

class pulp::signal::BurstGenT< SampleType >
One trigger in, a burst of N triggers out, with a spacing curve and a level ramp.
Hit i of count fires at span * stage_curve(i / (count - 1), spacing_curve), where span = (count - 1) * spacing_ms. The curve is the shared stage-shaping law, so spacing_curve = 0 is even spacing, +1 accelerates (gaps shrink — a bouncing ball landing), and -1 decelerates (gaps grow — a drag).
RT contract: fixed scalar state; process() and reset() allocate nothing.
USE: ratchet fills; strum-like event fans; bouncing-ball gestures. Feed the output to LpgT::strike() with the per-hit level and you have a playable percussion roll from two primitives.
