{{/*

  Render a single HTTP API operation: that is, a method+endpoint combination, given:

  * `method`: the method, e.g. GET, PUT
  * `endpoint`: the endpoint
  * `operation_data`: the OpenAPI data for the operation
  * `anchor_base`: an optional prefix for the HTML IDs generated by
  this template.
  * `page`: the (Hugo) Page object to store endpoint metadata in the Scratch of. Used to build the endpoints TOC.
  * `module`: the current CS API module name, if any. Used to group endpoints in the TOC.

  This template renders the operation as a `<section>` containing:

    * an `<h1>` heading containing the method and endpoint
    * a `<details>` element containing the details, including:
      * operation description
      * basic info about the operation
      * request details
      * response details
