- Adjusted transition properties in components.css for better readability.
- Added new .workspace-link class in components.css for enhanced link styling.
- Changed config layout from grid to flex in config.css for better responsiveness.
- Updated related tests to reflect layout changes in config-layout.browser.test.ts.
