theme.css 为空或超过 256 KiB 限制

Error message

theme.css 为空或超过 256 KiB 限制

What it means

Thrown by parse_safe_css when the theme.css payload is empty or larger than CSS_LIMIT (256 KiB). parse_safe_css is the strict Safe CSS pre-parser for Dream Skin packages, so this fires before any rule parsing happens — a coarse size/emptiness gate on the raw css string extracted from the package. The offending input is the theme.css content itself.
