## Critical Gotchas
* The `formats` field controls the output shape and defaults to `["markdown"]`. Omitting it does not return HTML — request `["markdown","html"]` explicitly.
* `/crawl` is asynchronous: it returns a job `id`, and results are collected by polling `/crawl/{id}` until `status` is `completed`.
