Sending one 80 ms frame per RPC is ~12.5 gateway calls/s for as long as the ear is armed. Drain up to 4 queued frames into a single wake.feed payload (backend feed() already splits long buffers into engine frames) — ~3 RPCs/s steady-state. Fix the wake.feed size-cap comment (64000 bytes = 2 s, not 0.5 s).
