Dream Skin theme config exceeds 256 KiB

Error message

Dream Skin theme config exceeds 256 KiB

What it means

Size guard in save_dream_skin_theme: the serialized theme.json for a Dream Skin theme exceeds 256 KiB, so it would bloat theme storage and is rejected before writing. The offending input is an oversized draft config (usually from an imported package).

Solutions

1. Reduce the theme config size (trim CSS/custom data) before saving
2. Do not import packages with bloated theme.json payloads
3. Split content into multiple themes if legitimately large
