We use file name suffixes on all of these (except /) so URLs may easily
cached/memoized using a static file server.
+Encoding notes
+--------------
+
+Raw HTML and XML should only contain us-ascii characters which render
+to UTF-8.

+Plain text (raw message) endpoints display in the original encoding(s)
+of the original email.

Guidelines for using limited HTML
---------------------------------
We mainly use HTML for linking pages together with <a>.
browsers default to. So perhaps we will add different endpoints for
variable-width fonts.
-* Do not build <a> links from user-generated-content, this prevents
- public-inbox deployments from being turned into a spam linkfarm.
-
* No graphics, images, or icons at all. We tolerate, but do not
encourage the use of GUIs.
