Featured
button
Interactive button component with variants (default, destructive, outline, secondary, ghost, link), sizes, and composite ButtonGroup container for segmented toolbars and split buttons.
card
Bordered container with an opinionated header / content / footer layout. Use it as the wrapper around any self-contained block of content — settings panels, dashboard tiles, list cells.
sparkline
React mirror of @uipkge/sparkline — see the Vue registry item for the canonical description.
kanban-task-board
Full kanban task board surface: 4 status columns, drag-and-drop card movement with insertion indicator, board/list view toggle, search + priority + assignee filters, collapsible columns, click-to-open task detail Sheet (comments, subtasks, files), full-form Add Task Dialog with priority/assignee/due-date/tags/subtasks. Mega-block: ships 14 React files (KanbanBoard + 6 kanban-* views + 7 small badges/lists). Bind with columns/onColumnsChange; consumer owns the columns array so swapping the in-memory store for Drizzle/Postgres is a one-line change. Auto-pulls the use-kanban hook (types + configs + helpers) and kanban-data lib (seed columns).
notifications-popover
Header-grade notifications panel. Slot-trigger Popover the consumer wraps around their own Bell button. Filter tabs (All/Unread), Today/Earlier groups, category-coloured accent bars, hover-dismiss, mark-all-read, slide-in animation. Slot receives `unreadCount` so the trigger can show a badge.
ab-test-variant-results
Optimizely and Statsig style A/B test statistical significance scorecard and conversion delta comparison. Features experiment status header, 4 primary experiment metrics cards, variants comparison table with statistical verdicts, and conversion funnel step drop-off comparison.
