Application Shell 29 block design & features
ApplicationShell29 is an application shell built with Shadcn UI that adds a banner and a status bar around a standard sidebar layout. The banner announces the remaining trial days with an Upgrade button and a dismiss button.
The sidebar has a workspace button, primary links, a Projects group, settings links pinned low and the user menu in the footer. It starts below the banner and ends above the status bar, and moves up when the banner is dismissed.
The status bar is fixed along the bottom and shows system status, save state and branch on the left, with region, latency, version, Help and notifications on the right. The main area has a breadcrumb header and skeleton placeholder cards.
On small screens the banner shortens its message, the sidebar closes off-canvas and the status bar keeps only the essentials.
