{#
  vrf_yang.j2 — Produce a JSON array of VRF configuration objects.

  Input: GraphQL response from vrf_intent query.
  For each VRFDeviceAssignment, produce one VRF config entry with:
    - device-specific RD (falls back to VRF-level RD if not set on assignment)
    - L3VNI from the VRF's l3vni relationship
    - import/export targets: device-level if present, otherwise VRF-level
