《The Last Piano》动画短片
创建一个独立的 index.html：一部约 2 分钟的动画短片，名为 "the last piano"，采用手绘蜡笔和水彩风格。 场景：一个独眼发光的生锈小机器人在雨中穿过黑暗空旷的城市，在坏掉的路灯下发现了一架旧立式钢琴。后来一只黑猫出现聆听。 音乐：创作一首原创钢琴曲（Am - F - C - G）并使用 Web Audio 合成。它从一个不确定的音符开始，逐渐发展为完整的和弦。 同步：一条时间线驱动两者。机器人的手按下实际发声的琴键。每个音符点亮城市中的一扇窗，雨变成雪，最后的和弦点亮所有剩余的一切。 规则：仅使用 Canvas 2D，无库，无外部资源。

Create a single self-contained index.html: a ~2-minute animated short called "the last piano", in a hand-drawn crayon and watercolor style. Scene: a small rusty robot with one glowing eye walks through a dark, empty city in the rain and finds an old upright piano under a broken streetlamp. Later a black cat shows up to listen. Music: compose an original piano piece (Am - F - C - G) and synthesize it in Web Audio. It starts with one unsure note and grows into full chords. Sync: one timeline drives both. The robot's hands hit the keys that are actually sounding. Every note turns on a window in the city, the rain turns to snow, and the final chord lights up everything that's left. Rules: Canvas 2D only, no libraries, no external assets.
