-  * For security reasons, some headers can only be controller by the user agent. These headers include the forbidden
-  * header names and forbidden response header names.
-  *
-  * A Headers object also has an associated guard, which takes a value of immutable, request, request-no-cors, response,
-  * or none. This affects whether the set(), delete(), and append() methods will mutate the header. For more information
-  * see Guard.

+/** [[https://fetch.spec.whatwg.org/#headers-class ¶6.1 Headers Class]] of whatwg spec
+  *
+  * The Headers interface of the Fetch API allows you to perform various actions on HTTP request and response headers.
+  * These actions include retrieving, setting, adding to, and removing. A Headers object has an associated header list,
+  * which is initially empty and consists of zero or more name and value pairs. You can add to this using methods like
+  * append() (see Examples.) In all methods of this interface, header names are matched by case-insensitive byte
+  * sequence.
+  *
+  * For security reasons, some headers can only be controller by the user agent. These headers include the forbidden
+  * header names and forbidden response header names.
+  *
+  * A Headers object also has an associated guard, which takes a value of immutable, request, request-no-cors, response,
+  * or none. This affects whether the set(), delete(), and append() methods will mutate the header. For more information
+  * see Guard.
+  *
+  * You can retrieve a Headers object via the Request.headers and Response.headers properties, and create a new Headers
+  * object using the Headers.Headers() constructor.

-  * The events needed to handle generic pointer input are analogous to mouse events (mousedown/pointerdown,
