Add comprehensive rule to detect and prevent empty CSS style blocks:
- Identify style objects with no properties
- Flag empty style blocks as potential code quality issues
- Provide auto-fix capability to remove empty blocks
- Handle edge cases like comments-only blocks
This rule helps maintain cleaner codebases by eliminating empty style definitions that often result from incomplete refactoring or forgotten implementations, reducing confusion and unnecessary code.
Add comprehensive tests for shared utility modules to improve code coverage:
- Test property name extraction edge cases
- Test CSS property priority map with invalid groups
- Test order strategy visitor creator edge cases
- Test font face property order enforcer early returns
- Test style node processor with arrays and null values
These tests ensure all code paths in shared utilities are properly exercised,
including error handling and edge cases.
