  title: Cloudflare Rotate Load Balancer
  summary: Create a load balancer, update its pools, then delete it.
  description: >-
    A full lifecycle for a single load balancer. The workflow creates a load
    balancer over an initial set of pools, updates it to use a new default pool
    set, and deletes it once the change is applied, threading the load balancer
    identifier from step to step. Each step inlines its request and asserts both
    the documented HTTP 200 status and the Cloudflare {success, result} envelope
    flag.
