+{-| Throughout the Elm SDK, there are lots of pieces of text being used for

+
+  - To log on what is happening during an API call.
+  - To fail with custom decoder errors.
+  - To describe custom values in a human readable format.
+
+All magic values of text are gathered in this module, to form a monolithic
+source of text. This allows people to learn more about the Elm SDK, and it

+1.  The homeserver is very archaic and does not (yet) support API endpoints that

+2.  The homeserver is much more modern than the Elm SDK and either uses
