Phase 1: Story Planning       → Break story into scenes (Claude reasoning, no ComfyUI)
Phase 2: Hero + Refs          → Z-Image: 1 hero frame + character ref portraits + background ref
Phase 3: Hero Review          → Visual verify hero and refs, user approves
Phase 4: Edit Chain           → Qwen Edit: chain ALL scene frames from hero (with char refs in slots 2-3)
Phase 5: Frame Review         → Visual verify all frames, approve/reject/retry
Phase 6: Video Clips          → WAN 2.2 FLF dual Hi-Lo (one clip per scene)
Phase 7: Video Review         → Preview each clip
Phase 8: Final Assembly       → ffmpeg concat all clips into one MP4

Scene 1: S1_start (unique)        → hero (end)
Scene 2: hero (= S1 end)          → S2_end

Hero (man+cat on bed)
  ├─ S1 Start: edit hero → remove cat, man alone
  ├─ S2 End: edit hero → replace cat with woman
  │    └─ S3 End: edit S2End → both sit up, man startled
  │         └─ S4 End: edit S3End → sitting close, warm smiles
  │              └─ S5 End: edit S4End → warm embrace
