蜡笔风格钢琴演奏动画
创建一个独立的 index.html：一段约 2 分钟的蜡笔手绘风格钢琴演奏动画。 场景：夜晚温馨的房间里，一架立式钢琴，一只小黑猫正在弹奏。所有表面均呈现蜡笔质感：颗粒状笔触、抖动的轮廓线、纸张纹理。 音乐：创作一首原创钢琴曲（约 40 小节，旋律清晰，情绪从平静逐渐增强，结尾柔和）。使用 Web Audio API 合成钢琴音色，包含泛音、击弦噪声和混响效果。不使用任何音频文件。 同步：单一时间轴驱动画面与声音。猫的爪子精准敲击实际发声的琴键。灯光、镜头视角和氛围随音乐变化。 规则：仅使用 Canvas 2D，不引入任何库或外部资源。支持暂停/重播功能，并通过 ?t=90 参数跳转至任意时间点。

Create a single self-contained index.html: a ~2-minute animated piano performance in a hand-drawn crayon style. Scene: a cozy room at night, an upright piano, a small black cat playing it. Crayon texture on every surface: grainy strokes,wobbly outlines, paper tooth. Music: compose an original piano piece (~40 bars, clear melody, calm then building, soft ending). Synthesize the piano in Web Audio with harmonics, hammer noise and reverb. No audio files. Sync: one timeline drives both. The cat's paws hit the keys that are actually sounding. Lights, camera and mood follow the music. Rules: Canvas 2D only, no libraries, no external assets. Support pause/replay and ?t=90 to jump to any moment.
