Mock, issue #2570

The sidebar, sorted into groups

Only the sidebar is real here: the app's own markup, sizes and colours, on white with rounded corners. Rows respond to hover and click, Dossiers fold, and the button at the top right of the sidebar collapses it to the icon rail. Nothing navigates, and the Dossier names are invented.
