 *   defines a request body content type. Uses the selected content type from the operation or the
 *   first defined request body content type. Omitted when the selection is `none` or `other`.
 * - Accept: Derived from the 2xx response content types in the spec (joined as a comma-separated list), falling back to a wildcard.
 * - User-Agent: Added in Electron environments (desktop app or proxy) to identify the client.
 *
 * @param hideDisabledHeaders If true, filters out headers marked as disabled for this example via
 *   `x-scalar-disable-parameters.default-headers`.
 * @param hideOverriddenHeaders If true, omits any default header whose name matches an **enabled**
 *   operation parameter with `in: header` (disabled optional header parameters do not shadow defaults).
