Contributed an HTML formatter enhancement to the biomejs/biome repository, focusing on improving readability for elements with multiple attributes in multiline configurations. The solution introduced logic to insert a hard line break only when the attribute position is multiline and more than one attribute is present, aligning formatter behavior with established configuration rules. This targeted change was implemented in Rust and involved code refactoring, HTML formatting, and thorough testing to ensure maintainability and consistency. By delivering a focused update with minimal surface area, the work reduced review complexity and risk, ultimately supporting developer productivity and cleaner code across the project.
