@rahhal/ui/kanbanKanban board
Column-based task board layout primitive. Provides the board frame, columns (with title / count / accent dot / action), and cards (with title / description / leading / trailing / meta slots). Layout only — apps wire drag-and-drop with their own DnD library (e.g. `@dnd-kit/core`). On small screens columns stack and snap-scroll horizontally so swipes feel native.
