// Public API for `@barefootjs/xyflow`.
//
// JSX-native renderer components (`<Flow>` / `<Background>` /
// `<Controls>` / `<MiniMap>` / `<Handle>` / `<NodeWrapper>` /
// `<SimpleEdge>`) are distributed via the shadcn registry at
// `ui/components/ui/xyflow/` — install with `bf add xyflow`.
// This package ships the utility helpers, types, signal hooks, store,
// and the imperative pointer-paced subsystems those components attach
// via `ref` callbacks.

// Store / context / signal hooks

// callbacks. JSX gives these no leverage — pan/zoom is owned by
// `XYPanZoom` (D3-zoom-derived), the selection rectangle owns global
// pointer capture, connection drag uses `elementFromPoint`, and the
// node resizer needs raw dimension math.
