facett-kanban — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: A pure-egui Kanban board facet: status columns, drag-to-transition, swimlanes, WIP limits.
• Does: Renders cases as draggable Cards in Columns (one per workflow status), optionally grouped into swimlanes (assignee/priority/kind) with per-column WIP limits. Dragging a card to another column records a Move; the host drains take_moves() to fire (and validate) the real workflow transition. Board follows the facett Facet contract (title/ui/state_json); the widget itself does no state mutation of the domain.
• Key deps: egui, serde/serde_json. Optional facett feature (off by default) to impl facett_core::Facet; compiles egui-only otherwise to stay robust against facett-repo churn.
• Shape: lib, ~386 LOC single lib.rs (Column, Card, Priority, Move, Board).
• Observed role in the workspace: Consumed by ordning-gui::kanban_view (the only widget with an in-repo consumer). Built in ordning temporarily; destined for the facett repo.

• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
