   The reference. Laid out the way generated API documentation is laid out,
   because that is what a client arriving at a base URL expects to find: an
   operation list, a coloured method, a parameter table, a response table, and
   somewhere to send a live call from.

   All of it is server-rendered. The obvious way to get this look is to ship a
   bundled documentation viewer, but those render client-side, and a client that
   reads with a fetch tool would receive an empty mount point and a script tag.
   Everything here survives being converted to text, which is how most of our
   traffic reads it. <details> is open by default for the same reason.
