+ * A custom Error used to return a more nuanced error detailing _why_ one of the eight documented
+ * errors in the spec was raised after calling `navigator.credentials.create()` or
+ * `navigator.credentials.get()`:
+ *
+ * - `AbortError`
+ * - `ConstraintError`
+ * - `InvalidStateError`
+ * - `NotAllowedError`
+ * - `NotSupportedError`
+ * - `SecurityError`
+ * - `TypeError`
+ * - `UnknownError`
+ *
+ * Error messages were determined through investigation of the spec to determine under which
+ * scenarios a given error would be raised.
