迭代式镜头切换 85mm（Edit Prompt 工作流）

Style: Continuation of a previous Sora 2 generation. Maintain the locked aesthetic — same wardrobe, same set dressing, same color grade. Only change what is specified below. Reference: same subject, same location, same lighting setup as the original clip. Cinematography (changes only): - Same shot, switch to 85mm - Shallower depth of field; tighter framing on the subject's eyes and hands - Keep camera height and angle identical to the original Actions (unchanged): - Subject performs the original action exactly as before; do not re-block, do not re-light Background Sound: Identical to the original — diegetic only, no added score. Production note: this is an EDIT prompt, not a fresh generation. Pin the original as reference and describe only the change ("same shot, switch to 85mm"). Sora 2 Edit endpoint: POST /v1/videos/{video_id}/edits.
