/**
 * Combat SFX wiring check (dev tool, run with Node + a CDP browser):
 *
 *   node dev/combat.sfxcheck.mjs
 *
 * Drives REAL game events in BOTH combat contexts — the range
 * (http://127.0.0.1:8080/combat) and the main game
 * (http://127.0.0.1:8080/index.html?combat) — and asserts that each of
 * the seven combat events (fire / impact / shield / hull / kill /
 * down / respawn) went through the SHARED SFX path
 * (js/combat/CombatSfx.js → window.__COMBAT_SFX__ dev log) — and, in
 * the main game, the EIGHTH event, levelup (the combat level landing —
 * the run's XP bank, fed through the dev hook).
 *
 * Why a log: a headless browser has no audio manager, so the shared
 * guards (js/utils/Sfx.js) stay silent — the dev log records the call
 * itself, which is exactly the wiring under test. In a real browser
 * the same calls play the data/sfx.json voices.
 *
 * Requires: the dev server on :8080 (node dev/server.mjs 8080) and a
 * headless Chromium/Brave with CDP on 127.0.0.1:9333 (see dev/cdp-shot.mjs).
