Audio: distant birds, quiet room tone, guzheng single notes fading in

[Shot6 6-12s 花坠落]

Negative: confetti, metallic glitter, cherry blossom pink petals (must be golden tiny osmanthus), snowflakes

[Shot7 12-20s 奶纹与热气]

Post: 所有中文与logo后期合成，禁止AI渲染文字

1. 音乐：A版15秒用轻盈风铃+轻快节拍，第3秒注水声卡点；B版30秒古筝+氛围pad，留白多、不煽情
2. 同期声优先级：注茶声、吸气第一口、杯壁水珠、碰杯四样必须真实近景收音感，禁用咖啡馆嘈杂人声喧宾夺主
3. 调色：秋日暖金+檀木棕+奶白三色，茶汤琥珀色必须通透；任何偏荧光黄、偏橙的画面重跑
4. 竖屏纪律：所有主体在中部70%安全区，上下预留抖音UI遮挡；杯身永远完整不贴边裁切
5. 版本切片：从B版拆桂花坠落6秒做评论区置顶素材；截注茶帧做小红书封面；A版前3秒单独导出做搜索广告
6. 合规：不出现「治愈/养生/保健」功效词；桂花与茶为食品不是药品；门店画面不拍到其他品牌招牌
