Hook DNA established.)\n(Mix: Intimate, centered low-end.)\n\n[verse]\n(Chords: Gmaj7 - Cmaj7 - Gmaj7 - Cmaj7)\n(Vocal-Perf: Breathy, almost spoken chest voice. Conversational rhythm.)\n(Inst: Bass and drums carry the groove. Guitar plays sparse, percussive counter-melodies.)\n拖鞋放在门口好几天没动\n你说要来 又没来\n冰箱里还留着你喜欢的椰冻\n我没舍得 吃掉它\n\n[pre-chorus]\n(Chords: Am7 - D7 - Gmaj7 - Cmaj7)\n(Vocal-Perf: Melody becomes more sung, rising slightly in pitch. Builds gentle anticipation.)\n(Transition: Subtle synth pad swells underneath.)\n其实我懂\n你只是怕\n靠近了又要退回去\n像潮水涨 又落下\n\n[chorus]\n(Chords: Gmaj7 - Cmaj7 - Am7 - D7)\n(Vocal-Perf: Rhythmic, catchy hook delivered in a soft, breathy tone. Light background harmonies enter.)\n(Mix: Vocals upfront and centered. Stereo width increases with guitar layers.)\n(Inst: Groove is full but remains laid-back. Bassline is more active.)\n慢半拍 慢半拍\n就这样也挺好\n你不说我也猜\n嗯\n心都在\n慢半拍 慢\n别人都说说走就走天亮就散场\n偏偏你还在这里\n陪我等天光\n\n[bridge]\n(Chords: Em7 - A7 - Cmaj7 - Gmaj7)\n(Vocal-Perf: Shifts to a more emotional, sustained falsetto. More dynamic contrast.)\n(Inst: Harmony shifts, creating a feeling of reflection. Guitar chords are more present.)\n(Transition: Beat simplifies, leaving more space for the vocals.)\n要是没有你（要是没有你）\n这安静算什么呢\n要是没有你\n这夜晚 给谁看呢\n\n[verse]\n(Chords: Gmaj7 - Cmaj7 - Gmaj7 - Cmaj7)\n(Vocal-Perf: Returns to conversational chest voice, slightly more confident delivery.)\n(Inst: Groove re-establishes, funky guitar licks become more prominent.)\n窗台上那盆薄荷长得很好\n是你带来的 记得吗\n你说浇水别太多 三天一次刚刚好\n我每次都多浇了一点点\n\n[chorus]\n(Chords: Gmaj7 - Cmaj7 - Am7 - D7 - Em7 - A7 - Cmaj7 - Gmaj7)\n(Vocal-Perf: Higher energy, more ad-libs and falsetto runs. Layered harmonies are richer.)\n(Mix: Widest point of the track. Vocals feel fully immersive.)\n(Sound-Design: A subtle reverse cymbal leads in.)\n慢半拍 慢半拍\n就这样也挺好\n你不说我也猜\n嗯\n心都在\n慢半拍 慢\n别人都说说走就走天亮就散场\n偏偏你还在这里\n陪我等天光\n要是没有你\n这夜晚 给谁看呢\n\n[outro]\n(Chords: Gmaj7 - Cmaj7)\n(Vocal-Perf: Improvised, breathy falsetto ad-libs fading out.)\n(Inst: Beat and bassline slowly fade, leaving a final muted guitar chord.)\n(Structure: Fade out.)\n要是没有你\n这安静 算什么呢",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：深沉的暮色靛蓝与柔和的米灰色相互渗透，边缘透出一缕极淡的暖琥珀，像夜晚窗玻璃内侧凝结的水汽，带着安静的体温和若有若无的留恋感。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
