/**
 * Combat SFX — ONE shared event→voice map for both combat contexts (the
 * range: js/combat/CombatScene.js, and the main game: js/combat/CombatSystem.js).
 * The contexts call `combatSfx(scene, event)` at their event sites; the
 * map + the playback path live HERE, so the two contexts can never drift.
 *
 * Every event gets a DISTINCT voice from the data/sfx.json set — the two
 * cannon voices ride the new assets/fx/combat-mass-cannon*.mp3 files, the
 * rest the existing set:
 *
 *   cannon_fire  mass_cannon      the player's cannon going off (the new
 *                                 combat-mass-cannon.mp3)
 *   cannon_hit   mass_cannon_hit  the player's tracer striking a hostile
 *                                 (the new combat-mass-cannon-hit.mp3)
 *   fire         laser            the ENEMY's laser going off (the new
 *                                 combat-laser.mp3 — the player's cannon
 *                                 plays cannon_fire; the laser plays at
 *                                 the same volume)
 *   impact       ui_click         the light tick of a tracer striking (the
 *                                 player being hit, wall ticks — a hostile
 *                                 taking the player's shot plays cannon_hit)
 *   shield       solar_buzz       the energy shimmer of a field absorbing
 *   hull         mining_split     the heavy crack of armor taking the hit
 *   kill         thunder_01..04   one at random — the boom of a ship dying
 *   down         deconstruct      the player's death (the collapse voice)
 *   respawn      discovery        the player reforming (the "new object in
 *                                 view" voice)
 *   levelup      solar_flare_01   the combat level landing (the charge-rise
 *                                 voice — js/combat/XpManager.js's 'levelup'
 *                                 event, subscribed by CombatSystem)
 *
 * Playback goes through the shared Sfx.js guards (master switch, audio
 * manager, cache) — a headless scene with no manager simply doesn't
 * sound, but the dev log below still records the call.
