  "lyrics": "[verse]\n(Chords: Ebmaj7 - G7/D - Cm7 - F9 - Fm7 - Bb7sus4 - Ebmaj7)\n(Vocal-Perf: Gentle chest voice; Breathy delivery; Mezzo-piano)\n(Mix: Vocals centered and forward; Piano wide; Intimate space)\n(Inst: Flowing piano arpeggios providing harmonic bed)\nI kept your sweater in the drawer\nThe one you left beside my door\nSome mornings I forget, and then\nI smell the wool and lose again\n\n[verse]\n(Transition: Piano fill connects sections smoothly)\n(Chords: Ebmaj7 - Dm7(b5) - G7 - Cm7 - F9 - Fm7 - Bb7sus4 - Ebmaj7)\n(Vocal-Perf: Consistent gentle tone; Slight dynamic swell)\n(Inst: Piano arpeggios continue, with subtle harmonic variations)\nThe kettle clicks the way it did\nWhen you were here, before we slid\nInto the quiet — two cups poured\nAnd one left cooling on the board\n\n[bridge]\n(Transition: Piano shifts to block chords, key change feel)\n(Chords: Bmaj7 - Bbm7 - Eb7 - Abmaj7 - Gm7 - C7 - Fm7 - Bbm7 - Eb7)\n(Vocal-Perf: More dynamic and emotional; Rises into a soft falsetto)\n(Mix: Reverb becomes slightly more noticeable on vocal highlights)\n(Inst: Piano plays richer, block chords to emphasize the emotional shift)\nAnd I have walked the length of every room\nPressing my thumb against the spot\nWhere your coat hook bent the plaster\nProof of you that I cannot unknot\nThis is what remaining feels like —\nNot a wound, but something slower\n\n[verse]\n(Transition: Piano returns to arpeggiated style, resolving back to home key)\n(Chords: Ebmaj7 - G7/D - Cm7 - F9 - Fm7 - Bb7sus4 - Ebmaj7)\n(Vocal-Perf: Returns to softer, intimate delivery)\n(Inst: Gentle piano arpeggios resume)\nThe answering machine still holds\nYour voice between the other calls\nSeven seconds, nothing said —\nJust breath, and then the dial tone, dead\n\n[interlude]\n(Chords: Ebmaj7 - G7 - Cm7 - F9 - Fm7 - Bb7 - Bmaj7 - Bbm7 - Eb7 - Abmaj7)\n(Vocal-Perf: None)\n(Mix: Piano takes center stage; Stereo field feels wider)\n(Inst: Expressive solo piano melody with jazz flourishes and arpeggiated runs across the keyboard)\n\n[bridge]\n(Transition: Piano builds intensity into the final vocal entrance)\n(Chords: Bmaj7 - Bbm7 - Eb7 - Abmaj7 - Gm7 - C7 - Fm7 - Bbm7 - Eb7)\n(Vocal-Perf: Most powerful delivery; Emotional peak; Sustained high notes in head voice)\n(Inst: Piano plays strong, resonant chords with more dynamics)\nAnd I have stood inside the doorway\nOf the life we almost chose\nClose enough to feel the warmth there\nFar enough to feel it close\nThis is what the quiet undertow does —\nPulls you deep without a warning\n\n[outro]\n(Transition: Decrescendo into a final, gentle resolution)\n(Chords: Ebmaj7 - G7/D - Cm7 - F9 - Fm7 - Bb7 - Ebmaj9)\n(Vocal-Perf: Fading dynamics; Breathy and tender; Final phrase descends into a whisper)\n(Mix: Gradual fade out; Reverb tail lingers)\n(Inst: Piano slows down, playing final arpeggios and a sustained closing chord)\nI kept your sweater in the drawer\nI don't know what I kept it for\nMaybe just to hold the weight\nOf all the things I said too late\nAll the things I said too late\nToo late",
  "cover_prompt": "生成一张极简主义的抽象环境光晕（Ambient Aura）图片作为无字音乐专辑封面。画面的核心色彩组合与情绪倾向是：深沉而温柔的蓝灰渐变，边缘渗入一缕暖黄——像清晨阳光透过厚窗帘缝隙落在旧木地板上，却又无力驱散整片阴凉；远端隐约浮现极淡的薰衣草紫，像记忆边缘将散未散的气息。画面完全由纯粹的色彩构成，采用极度的柔焦（Soft focus）和重度模糊效果（Blurred effect），使得不同颜色之间产生极其平滑、如丝绸般的无缝过渡。整体质感极致平滑细腻（Smooth texture），没有任何杂质。强烈要求：这是一张彻底抽象的现代色彩场（Color Field）作品，绝对不要出现任何具体的物体、几何图案或锐利的边缘！不需要任何胶片颗粒感！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母，不要生成人物轮廓！传达出一种极其平静、舒缓、现代且充满呼吸感的氛围。",
