Continued expanding ScholarOS into a production-ready web desktop for students. This update focused on improving both usability and productivity while keeping everything local-first.

✅ Added
Formula Sheet app with categorized SAT Math references, search, favorites, and copy support.
Calendar Lite with Today, Week, and Upcoming views, event management, and study block presets.
Focus Mode and Workspace Layouts for quickly switching between different study environments.
Improved backup and restore support to include the new apps and settings.
Better window management, local storage recovery, and overall desktop polish.

🛠 Technical Improvements
Added reusable utilities and data models.
Expanded unit and Playwright end-to-end test coverage.
Improved application architecture and documentation.
Verified the project with linting, production builds, and automated tests.

🚀 Next
I’m now working on adding a Command Palette, desktop widgets, and more advanced operating system features to make ScholarOS feel even closer to a real desktop environment while remaining completely browser-based.
