// Pins the Phase 0.b compat decision (docs/audio-engine-tlc.md §4): native
// gain clamp bounds are 0..32 — matching the audio-effects executor's JS-side
// clampGain so a legit high rig gain is never under-shot — with NaN/Inf
// rejected universally; stream/renderer-bus gains keep the tighter 0..8.
