/**
 * Stable CSS class names for xyflow primitives.
 *
 * Exported as constants so the registry-side `<Flow>` / `<Background>` /
 * etc. can reference them via `className={BF_FLOW}` instead of
 * `className="bf-flow"`. site/ui's `cssLayerPrefixer` only rewrites
 * locally-declared static `className` literals; imported identifiers are
 * left alone, which keeps `bf-flow*` un-prefixed for the e2e selectors
 * (the same trick chart uses with `CHART_CLASS_GRID` etc.).
