// Test the CFW buzzer / UI-sound path (load_image_z mode 5).
//
// REQUIRES the CFW build whose load_image_z dispatches mode 5 to the firmware
// buzzer driver. A "sound message" is just an ordinary ImageRawData update whose
// reassembled buffer starts with 0x05 — it flows through the same image handler,
// but instead of touching the display it queues a tone and returns immediately.
//
// wire buffer = [0x05][kind][args...]
// kind 0 [5][0][type] preset 0..8 (DRV_BuzzerPlayAfterQueue)
// kind 1 [5][1][note][oct][beat] one tone (DRV_BuzzerPlayNote)
// note 1..7, oct 0..3, beat = duration in ~62ms units
// kind 2 [5][2] stop / silence
//
// PRIMARY QUESTION: does playing a sound BLOCK the firmware until the sound
// finishes, or is it fire-and-forget (osTimer-driven)? We answer it by timing
// each send from write to ack. A short beep gives the baseline message latency;
// a long preset (the ~15x repeating alarm, several seconds of audio) is sent
// right after. If its ack latency ~= the baseline, the driver is async and the
// CPU is free while the sound plays. If the ack is delayed by seconds, it blocks.
//
// bun examples/sound-test.ts
//
// Env: G2_ARM=L|R (default R), G2_SOUND_ALARM=0 to skip the long alarm test.
