-// endpoint serving `Vec<hive_jobq_wire::GraphNode>` works — see
-// hive-jobq-wire's README). Renders an indented state tree:
-// `payload.label` verbatim, `payload.data` as a generic key/value list.
-// Light DOM, shared by the dashboard and swarm-ui — both esbuild
-// configs run `jsx: 'automatic', jsxImportSource: 'preact'`, so this
-// file is real JSX in either build, not hand-written `h()` calls.
-//
-// `cancellable` adds a per-node cancel button calling `onCancel(id)`
-// directly (a plain prop). `onUpdate(nodes)` fires after every fetch,
-// for a host needing the raw list (a count badge, a live-log panel)
-// without its own parallel fetch.
-//
-// Two ways to use this: JSX (swarm-ui, or any future dashboard page
-// that renders it directly) — `<JobqGraph endpoint="..." cancellable
-// onCancel={...} onUpdate={...} />`, a normal component. Or imperative
-// mount (dashboard/src/builds.js, which stays plain `.js` — a `.jsx`
-// call site still needs a JSX-aware file, mounting doesn't) —
-// `mountJobqGraph(container, props)` returns a `{ refresh(),
-// update(props) }` handle.
-//
-// Styles live in `@hive/shared/jobq-graph.css`, `@import`ed from a
-// page/component CSS file rather than imported here. This one stays
-// necessary regardless of the JSX question above: dashboard bundles
-// every page entry (including this component, pulled in transitively)
-// through one esbuild call whose `.css` loader is `text` — a handful of
-// shadow-DOM components (modal.js, hive-btn.js) need their CSS as a
-// literal string to inject into a shadow root, and esbuild's loader map
-// is global per call, not per-module. Importing `.css` here would
-// silently pick up that `text` loader too and bind a useless string
-// instead of applying styles, so this file imports no CSS at all;
-// each consumer's own page/component CSS `@import`s it instead.

+// floor every jobq gets for free.
+//
+// `Node`-kind dep edges get a plain "waits on: <label>" text line — see
+// `buildTree`'s `_waitsOn` resolution. `cancellable` attribute adds a
+// per-node cancel button dispatching `hive-jobq-graph-cancel` instead of
+// POSTing anything itself — see `CANCELLABLE_STATES` + the click-delegate

+// `.render(nodes)` renders host-pushed data directly, no fetch. Every
