3 crates with 3 HP each degrade from solid → damaged → critical → destroyed. New in Step 4: health bars above players, muzzle flash on fire, hit feedback (white flash + particles + camera shake), score bounce animation, and Web Audio sound effects — gunshots, hits, deaths, crate explosions, and win jingle.
Sounds generated via Web Audio API — no downloads needed. Gunshots, hit thuds, death tones, crate explosions, and a win arpeggio. Audio context created lazily on first interaction to comply with autoplay policy.
Each player has 5 HP displayed as a bar above their sprite. Color transitions: green (full) → yellow (3-4 HP) → red (1-2 HP). On hit, player flashes white and bursts particles. At 0 HP they respawn and opponent scores a point.
