Product media placeholder
Replace this area with a screenshot or short walkthrough video during the media sweep.
Integrates `value` per frame and emits a `pulse` each time the running total reaches `threshold`, then subtracts threshold from the accumulator (overshoot carries forward). `maxBacklog` clamps post-fire overshoot so a one-frame burst cannot queue an unbounded backlog.

Use cases
- Distance-since-last-spawn triggering — feed cursor velocity (px/frame) and spawn rate becomes proportional to speed (slow = infrequent, fast = frequent). Cursor trail, image trail.
- Per-N-units events — fire every Npx of scroll, every N units of accumulated motion, every N items processed.
- Rate-limited emission from a continuous signal — convert a noisy / continuous quantity into discrete pulses paced by accumulated magnitude.
Envelope
Use accumulatePulse as the node type inside a graph node envelope. Add id, optional params, optional connections, and optional activeWhen based on the guide context.
