首图提示词：
Vertical 24:43 photorealistic smartphone image inside a subway carriage. An adult woman with long straight dark hair and a slim build sits centrally on a deep red upholstered bench, her legs crossed with the upper foot extending toward screen left. She looks down at a gray triple-camera smartphone held in both hands. She wears a fitted white sleeveless collared button-front top, black shorts, white ribbed ankle socks, and reflective silver pointed-toe heels. A white rectangular gift box with a small dark wordmark rests across her lap. A pale shoulder bag hangs from a fine chain on her screen-left side; pale bracelets are visible at her wrist.
A large dark-edged phone held by a hand fills the lower-right foreground, tilted slightly inward. Its white shopping screen shows a black floral-lace bodysuit and a pair of long stockings arranged as a product set, with small controls along the bottom and a magenta button at bottom right. Two seated passengers flank the woman, partially cropped: blue top, long gray skirt and brown handbag on screen left; gray knitwear and a dark bag on screen right. Silver metal walls, dark windows, a straight chrome pole immediately to the woman's screen right, and a mustard-yellow speckled floor establish the carriage. Frontal, slightly low viewpoint, even cool indoor light, soft shadows and natural skin texture.

[Shot 1] 拍摄持续15秒的单手手持连续镜头，画面近乎静止开场，伴随轻微手持晃动，取景集中在车厢内的女子身上。前景一只手握着一部深色边框的大屏手机伸入画面右下角，手机为白色购物页面，下方一排横向的小型商品缩略图。画面中的女子保持参考图形象：黑色长直发、身材比例、面色自然，浅色链条肩包垂挂身侧，白色礼物盒横放膝上，盒上印有 "DIOR" 字样，两侧邻座乘客、红色长椅、金属杆与银灰车厢背景均如参考图。她此刻穿着一件简洁的黑色连体泳衣，外搭白色无袖罩衫，双腿自然，脚踩银白色细跟凉鞋与白袜。初始穿衣状态固定，衣服颜色只在紫色光带扫过时改变。
0-2.5秒：她低头看着自己手机上正在浏览的页面，神情平静。前景操作手机的拇指沿着屏幕轻轻向右滑动，速度缓慢从容。
2.5-5.5秒：前景拇指停住，第一张商品图完整呈现——一件黑色一体式时尚连体泳装。此时一道淡紫色发光弧线自女子鞋踝缓慢升起，沿双腿向上扫过，银白细跟凉鞋与白袜变黑、白色罩衫被光带收走、黑色连体泳装显现并完整上身。更衣完成后光带渐隐，她仍平静低头，指腹停在屏幕上等待。
5.5-8.5秒：前景拇指再次轻轻向右滑动，切到第二张商品图——一条黑色丝绒吊带裙。又一道淡紫光带自肩颈向下缓缓掠过全身，黑色泳装变为黑色丝绒吊带裙，脚下变为黑色绒面细高跟。光带完全消散后，她稍抬起目光，看了眼自己换好的新装束，又垂回屏幕。
8.5-11秒：前景拇指第三次轻滑，切到第三张商品图——一套米白针织开衫配黑色阔腿裤。第三道淡紫光带自头顶向下缓缓扫过，黑色丝绒吊带裙变为米白针织开衫与黑色阔腿裤，鞋子换为米白平底。更衣停稳后她张了张嘴，露出惊讶。
11-13秒：前景拇指第四次轻滑，切到第四张商品图——一件湖蓝真丝衬衫与黑色半裙。第四道淡紫光带自胸口向下缓缓掠过，米白针织开衫变为湖蓝真丝衬衫，黑色阔腿裤收为黑色半裙，鞋换为黑色细跟。她从惊转为喜，嘴角上扬，垂眸看着自己的新装束。
13-15秒：前景拇指第五次轻缓滑动，切到最后一张商品图——一件白色优雅连衣裙。第五道淡紫光带再次自肩颈向下缓缓扫过全身，湖蓝衬衫与黑半裙变为一件白色合身连衣裙。她抬头看向完全变装后的自己，微微睁大双眼，停顿一瞬后露出满意的微笑，缓缓站起身，把膝上白盒与黑色购物袋并拢护在身前，镜头自下向上略微抬升，发梢短暂触到画面上缘，景别稳定在头至膝下。邻座乘客保持坐姿仅轻微转头，前景购物手机随她起身滑出画面底部。
全程她的脸部、黑色长直发、身材比例、浅色肩包与手腕配饰、邻座乘客、红色长椅、金属杆与车厢几何均保持如参考图，不改变。每次更衣中间她面部与身形不变，仅衣物随光带变化；手指滑动速度缓慢，每换完一身才切下一张。自然均匀的室内摄影光贯穿全片。无旁白、无台词、无字幕、无水印，画面不出现任何社交平台界面。
overall_soundscape: 前景拇指在玻璃屏幕上缓慢滑动的轻微摩擦声，每次滑入一张商品图时一声短促轻响；每次变装时衣料缓慢摩挲与光带掠过的轻短气声；末段提起购物袋时提手皮革与纸袋的轻微窸窣声；车厢行驶的低沉环境底噪极轻地贯穿全片。无任何对白或人声。
