/**
 * SFX voice test (dev tool, run with Node — no browser needed):
 *
 *   node dev/sfx.test.mjs
 *
 * Exercises the shared SFX voice (js/utils/Sfx.js) with a stub scene:
 * playSfxOn() guard rails (master switch off, missing sound manager,
 * asset not in the audio cache, the happy path, extra play options like
 * loop) and the stop/status helpers (stopSfxOn / sfxPlayingOn). Also
 * checks the sfx.json keys follow the play-name convention (sfx_<key>
 * cache key) and point at files that exist.
