/**
 * SoundAnalysisMIDIMode — sound analysis → MIDI CC output (audio_in input).
 *
 * Schema declares `primary_input: 'audio_in'` and `engine_id: 'thru'` (no
 * synthesis). Stream 10 wires the mic into channels 2..5 via ModeShell's
 * Mic button + the runtime's MicInput. The joystick is used as a fallback
 * for channels 0..1 and during testing without mic permissions.
 *
 * MIDI output routing is read-only here — the SettingsDrawer's per-param
 * override editor lets users tighten the active range / mute params; the
 * actual MIDI device wiring is left for the engine host to handle (or for
 * a future stream that adds WebMIDI sender). For now CC values are
 * visible in the live OutputDisplay.
