App Shell
A task tracker as a real app — the same tasks seen four ways (list, board, table, calendar) inside a rail, sticky bar and expanding capture field.
Note
Every part of this is redistributable — the sidebar, tabs and theme toggle were swapped off Animate UI and skiper so the page could ship. Composed from the library rather than hand-written: Data Table for the table view, Kanban for the board, Tree View for nested lists, animated Lucide icons driven by row hover, Number Flow and Sparkline for the stat strip. The full drag-and-resize calendar is a server component so it cannot nest in a client shell — but that wrapper only awaits static mocks, so the Calendar tab drives its providers directly and gets the full month/week/day/agenda calendar with drag and resize. Deliberately light on cards: the stat strip and task list are flush rules rather than boxes.
