// fabric_smoke.mjs — headless functional smoke test for surfaces/fabric.js (Dev2).
//
// Runs the REAL surface module under a minimal DOM + THREE + szl3d stub so we can
// prove, without a browser, that:
//   * the module mounts and starts a poll against the REAL /api/a11oy/v1/compute-pool
//   * a live compute-pool payload builds a node mesh (one group per node)
//   * sovereign nodes render gold, unreachable nodes get a red ring, GPU nodes pulse
//   * the fabric-health ring + HUD reflect counts read from the JSON (never fabricated)
//   * a 404 / degraded response degrades gracefully (no throw) + shows the honest state
//   * unmount() stops the poll and removes the DOM it added (no leak)
//
// Exit 0 + prints "FABRIC_SMOKE_OK n/n" on success; non-zero on any failed check.
// 0 runtime CDN; pure node stdlib + the authored module.
