### {date.today().isoformat()} - New Sheet LeeSoriV2 Conversion

User correction:

- The previous LeeSoriExtended puppet solved clipping but used the old LeeSori design.
- The authoritative new design sheet is:
  - `Characters_Build_Docs/LeeSori_Profile/03_Assets/Reference/sori_sheet.png`

Changed:

- Created `LeeSoriV2` from the new sheet's front full-body pose without AI identity drift.
- Extracted alpha-clean source and overlap puppet parts:
  - base, legs, chest, left/right arms, left/right hands, head.
- Replaced the app preview image with the new sheet-based LeeSori.
- Switched `characters.json` to:
  - `../Characters/Puppets/LeeSoriV2/rig.json`
  - `../Characters/Puppets/LeeSoriV2/Images/`
- Updated WebView framing for the new tall sheet ratio:
  - `right: 17.5%`
  - `bottom: -20%`
  - `width: 65%`
- Framing goal: upper-body biased view for idle/work states while keeping head and both hands visible. Full body remains available in the source/rig for later state-specific framing.

QA artifacts:

- `src/DansoriEQ.App/Assets/Characters/Puppets/LeeSoriV2/qa_source_black.png`
- `src/DansoriEQ.App/Assets/Characters/Puppets/LeeSoriV2/qa_view_390x600_upper_bias.png`
- `src/DansoriEQ.App/Assets/Characters/Puppets/LeeSoriV2/qa_view_390x600_css_selected.png`

Next:

- Build and run in WPF to verify real WebView framing.
- If this sheet-based puppet is accepted, add state-specific animation tuning and then generate Haruka/Isabel/Noeul with the same source-first process.
