March 2025 performance summary: Delivered a reusable Card UI component for Enact with support for multiple orientations, caption overlays, and selection states, accompanied by unit tests and documentation to accelerate UI development and ensure consistent design across apps. Fixed a critical DOM-prop propagation issue by removing the flip prop from the Icon component's rest props, reducing runtime errors and prop leakage. These efforts improved UI consistency, safety, and speed of feature delivery across projects.
