This version polishes the dashboard chrome and navigation.
- Sidebar navigation is easier to use: clicking a group’s chevron now only expands or collapses it, while clicking the label or icon takes you there. The chevron animates as the section opens and closes, and the toggle has proper keyboard and screen-reader support.
- The sidebar now uses a thin overlay scrollbar that widens when you hover or drag it, and a subtle gradient hints when more items are below the fold.
- The dashboard is now a fixed app-shell layout: the page itself no longer scrolls; instead, the content area scrolls independently, so the header and sidebar stay in place.
- The navigation loading bar is now purple to match the Noora theme.
