/* CONNECT — mobile first. No framework, no build: the file you edit is the file
   that runs.

   Khaki, and dark. The palette is one hue family — olive drab from near-black
   through to a dusty yellow-green — because a messenger is read for hours and a
   second competing hue is what makes an interface tiring. Colour is spent on
   three things only: what is yours, what needs attention, and what is dangerous.

   The shape borrows from the messenger everyone already knows how to use: an
   identity in the header rather than a hex string, one bubble per message with
   the time inside it, a composer whose right-hand button changes with what you
   are doing. Where it differs, it differs on purpose — the key of the person
   you are talking to stays visible, because here it is the only thing that
   actually identifies them. */
