FunPack StoryMem LoRA JSON Converter - supports both manual input and Qwen-generated output.

Features:
|
|
- Lenient parsing: auto-adjusts mismatched lengths for cut/first_frame_prompt
|
|
- Handles 'cut' as single bool (replicates) or list
|
|
- NO forced first cut=True (user can control via prompt or manual input)
|
|
- Safe defaults on invalid data → no crashes
|
|
- Splits full Qwen story into up to 3 separate scene JSONs
|
|
|
|
When use_qwen_output=False → uses manual per-scene inputs with the same leniency.
