   Type has three jobs and three faces, which is the whole system:
     Bricolage Grotesque  headlines. Optical-size aware, slightly odd, and not
                          one of the four grotesques every dev-tool site uses.
     IBM Plex Sans        prose. Engineered rather than neutral; it was drawn
                          for technical documentation and reads like it.
     IBM Plex Mono        anything the machine says - commands, values, hashes.

   Colour is not decorative. Mint, amber and coral are the app's own SAFE /
   CAUTION / RISKY labels, so a colour means the same thing on this page as it
   does inside the window.
