  "lyrics": "[intro]\n(Chords: F# - C# - D#m7 - Badd9)\n(Mix: Centered, intimate field)\n(Inst: Clean electric guitar arpeggios, single notes, light delay. Acoustic guitar enters with gentle strumming.)\n(Vocal-Perf: Breathy, wordless \"Mmm\" melody.)\n\n[verse]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Soft, conversational chest voice; mezzo-piano; clear diction.)\n(Inst: Bass guitar enters, playing root notes. Drums enter with a simple kick and closed hi-hat pattern.)\n(Melody-Contour: Mostly descending, reflective.)\n(Transition: Ride cymbal swell.)\n你说话的时候眼睛不看我\n我以为只是习惯了的距离\n手里的咖啡越来越凉了\n我还在等你继续说下去\n\n[pre-chorus]\n(Chords: Badd9 - C# - F# - C#/F)\n(Vocal-Perf: Dynamics build to mezzo-forte; more sustained notes.)\n(Inst: Full drum kit enters with snare on 2 and 4. Bass becomes more active.)\n(Melody-Rhythm: More flowing and lyrical.)\n(Transition: Drum fill.)\n那句话卡在喉咙里太久了\n咽下去以后什么味道都没有\n不是不想争 是争完了还在原地\n才明白有些结局早就写好了\n\n[chorus]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Strong, open-throated chest voice; forte; emotional emphasis.)\n(Inst: Overdriven electric guitar enters with sustained power chords, creating a wall of sound. Subtle string pads add width.)\n(Mix: Expands to full stereo width; vocals sit powerfully above the instrumentation.)\n(Melody-Contour: Ascending, anthemic lift.)\n爱你像钝刃割进掌心里\n不够深 却够疼\n最后还是我自己拔出去\n血迹干透才算清醒\n我没有怪你骗了我\n只是心疼那个信你的自己\n低过尘埃 跪过海底\n才懂得这一场温柔是钝器\n\n[interlude]\n(Chords: F# - C# - D#m7 - Badd9)\n(Inst: Lead electric guitar solo, melodic and distorted with long sustained notes and vibrato. Rhythm section is driving and tight.)\n(Mix: Guitar solo is front and center.)\n(Vocal-Perf: Distant, emotive vocal ad-libs float under the solo.)\n(Transition: Solo ends on a sustained note, feedback fades.)\n\n[bridge]\n(Chords: B - F# - C# - D#m7)\n(Inst: Instrumentation drops back, cleaner guitar tone, focus on arpeggios.)\n(Vocal-Perf: Airy, semi-improvised ad-libs.)\n(Mix: Dynamic drop, creates a moment of quiet reflection.)\n(Transition: Snare drum roll builds back into the chorus.)\n其实我也曾想过\n如果当初早些离开\n会不会少疼一截\n还是一样 伤口总得结痂\n\n[chorus]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Maximum emotional intensity; powerful ad-libs over the main vocal.)\n(Inst: All instruments at full power. Guitar solo motifs are layered in the background.)\n(Mix: Song's climax, dense and wide.)\n(Melody-Dev: Vocalist adds slight variations and embellishments.)\n爱你像钝刃割进掌心里\n不够深 却够疼\n最后还是我自己拔出去\n血迹干透才算清醒\n我没有怪你骗了我\n只是心疼那个信你的自己\n低过尘埃 跪过海底\n才懂得这一场温柔是钝器\n\n[outro]\n(Chords: F# - C# - D#m7 - Badd9)\n(Inst: Instruments fade out, leaving the arpeggiated clean electric guitar and a final melodic phrase from the lead guitar.)\n(Mix: Slow fade to silence.)\n(Structure: Fade out.)\n那个掌心的疤\n现在摸起来 不烫了",
  "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：深褐红与铁锈色在暗灰底色上缓慢渗透，像干涸后留下的痕迹，边缘晕散成暖调的赭石，中心压着一块沉重的深墨色，整体传递出隐忍后的钝痛与某种缓慢愈合的张力。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。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。",
