   Kanban idea board (/kanban)
   Layout + tile chrome for the board views. The .kanban-* class
   names and data-* hooks are emitted by app/views/kanban/**; the
   Stimulus kanban-drag controller relies on the data-* attributes,
   not on these styles. Themed to the app's Bootstrap palette via
   --bs-* variables so it follows light/dark.
