theme.css 只能选择 Skin API 注册的 data-ds-part

Error message

theme.css 只能选择 Skin API 注册的 data-ds-part

What it means

Selector whitelist guard in parse_safe_css: the selector does not begin with the literal prefix [data-ds-part=". The Safe CSS engine only styles elements registered through the Skin API via data-ds-part attributes; arbitrary selectors (tag, class, id) are refused.
