Mobile Game Treasure Chest Highlight Reward Animation

An original mobile-game "Highlight Moment" reward animation: a real 3D cartoon treasure chest built in Three.js, with five performance stages (standby, upgrade, charge, burst, and reveal). Rarity colors shift at each tier, and coins and gems fly into the balance with Web Audio sound effects. Delivered as a single-file web page, about an 18-second screen recording. Suited to game PV reels, gacha and loot-box reference animations, and game promo short videos.
