/* Repository viewer.

   No framework and no build step: the service ships as one binary, and a
   stylesheet that needed compiling would mean a toolchain in the release path.

   Written for people who have never used a code host: soft cards, plain words,
   big touch targets, and a repository front page that reads as a document. */
