theme.css 属性值不受 Safe CSS 支持：{property}

Error message

theme.css 属性值不受 Safe CSS 支持：{property}

What it means

Value whitelist guard in parse_safe_css: a property value is empty, longer than 512 chars, contains '{' '}' '<' '>' '!' or ';', or fails validate_property_value for that property. Only a curated set of safe values (colors, lengths, allowed filter functions) is supported per property.

Solutions

1. Use a value supported by Safe CSS for that property (e.g. plain color/length)
2. Remove forbidden characters (!, <, >, braces, semicolons) from the value
