  "prompt": "Genre: Mandopop / Ballad; BPM: 144; Key: C# Major; Rhythm: Slow, piano-led 4/4 groove. Sparse kick on 1, snare on 3. Cymbals swell for emotional emphasis.; Instruments: Resonant grand piano (arpeggios/chords), clean sub bass, simple drum kit (soft kick, wet snare), wide orchestral string pads swelling in choruses.; Vocals: Female. Breathy, intimate verses building to a powerful, clear belt in the chorus. Emotional delivery with controlled dynamics, from whisper to full voice.; Mood: The heavy silence in a car after the fight is over, watching streetlights pass in a blurry daze.; Production: High-fidelity, radio-ready polish. Wide, spacious mix with lush reverb. Vocals centered and upfront.; Language: Mandarin; Highlight: The sudden instrumental drop-out on the first word of the bridge, leaving the lead vocal exposed and vulnerable over a single sustained pad.",

  "lyrics": "[intro]\n(Chords: F#maj7 - C#maj7 - G#sus4 - G#)\n(Inst: Solo grand piano playing a gentle, arpeggiated motif with spacious reverb.)\n(Mix: Intimate and centered, establishing a melancholic tone.)\n\n[verse]\n(Chords: F# - C# - G# - A#m)\n(Vocal-Perf: Soft, breathy, conversational tone; mezzo-piano; close-mic intimacy.)\n(Inst: Piano continues arpeggios, supported by a warm, low sub-bass.)\n(Mix: Vocal is upfront and relatively dry, creating contrast with the ambient piano.)\n你离开那天我忘了开灯\n房间里只剩暖气的嗡鸣\n我以为时间会帮我稀释\n结果它只是改变了形\n\n[chorus]\n(Chords: F# - C# - G# - A#m)\n(Vocal-Perf: Stronger, clearer chest voice; dynamics build to mezzo-forte; more sustained phrasing.)\n(Inst: Simple drum pattern (kick on 1, snare on 3) enters. Lush string pads swell underneath, adding width and emotional weight.)\n(Mix: Stereo field widens significantly. Vocal gets a touch more reverb to blend into the larger arrangement.)\n(Transition: Cymbal swell and rising string intensity.)\n原来失去一个人\n不是在某一天突然失去\n是每天早上醒来\n又练习一次不去找你\n脚步停在厨房门口\n忘了只剩一个人吃饭这件事\n\n[verse]\n(Chords: D#m7 - G#7 - C#maj7 - C#maj7)\n(Vocal-Perf: Returns to a softer, introspective delivery; a sense of questioning.)\n(Inst: Drums and strings drop out, leaving a sparse texture of piano chords and bass.)\n(Mix: The soundscape narrows again, creating a dynamic drop and focusing attention on the lyrics.)\n(Transition: A clear rhythmic and melodic build-up with drums re-entering and strings swelling.)\n我把你的联系方式\n移到了一个不常打开的地方\n不是因为恨\n是因为太容易就想拨出去\n手指悬在半空里\n比开口道别更难的那种沉默\n\n[chorus]\n(Chords: F# - C# - G# - A#m)\n(Vocal-Perf: The most powerful and emotional delivery; forte dynamics; full-bodied belt with audible strain.)\n(Inst: Drums are more impactful with heavier compression. Strings are at their most prominent, driving the climax.)\n(Mix: The widest and loudest point of the song; all elements are present and powerful.)\n(Transition: Abrupt cut of most instruments at the end of the final phrase, leading into the bridge with just a sustained pad.)\n原来失去一个人\n不是在某一天突然失去\n是每天早上醒来\n又练习一次不去找你\n胸口里有个地方\n住着你但已经不等你回来的声音\n\n[bridge]\n(Chords: F#maj7 - G#sus4 - G# - C#maj7)\n(Vocal-Perf: Begins almost a cappella, exposed and vulnerable; builds back in intensity towards the end.)\n(Inst: Starts with only a high, shimmering string pad, then gentle piano chords re-enter to support the vocal.)\n(Mix: Extremely spacious and atmospheric; the vocal reverb tail is a key feature.)\n我没有恨你\n只是学会了在同一张床上\n把自己睡成两个人的宽度\n然后慢慢 再缩回来\n\n[outro]\n(Chords: F#maj7 - C#maj7 - G#sus4 - A#m7)\n(Inst: Full instrumental arrangement plays out, with the piano taking over the lead melody. Strings provide a final, lush chordal bed.)\n(Mix: Slow fade out, with the piano's reverb trail being the last element to disappear.)",
  "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：深冬清晨的蓝灰与褪色的暖白交叠，如同空置已久的房间里残存的一点体温——底层是沉静的石板蓝，向上渗入一片将散未散的淡奶白，边缘处浮现出极淡的赭石色晕染，像是暖气散出的最后一口热气凝在冷墙上。\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。",
