      "limits.cpu_ms: Maximum CPU time allowed per invocation, in milliseconds.",
      "Prerequisite: Limits are supported for the Standard Usage Model and are enforced only on Cloudflare’s network, not during local development.",
      "Docs conflict: The current configuration docs say the maximum is 50 for free accounts and 10,000,000 for paid accounts. The release-note example uses 150 without specifying a plan; the current docs’ free-account maximum conflicts with using 150 on a free account. https://developers.cloudflare.com/workers/wrangler/configuration/"
