//! **The founding half of the composer** (DESIGN §4.42 item 7; bl-673e): the
//! one line that names a workspace that does not exist yet and says what its
//! first conversation is for.
//!
//! It is the start's own box with one more word in front, and nothing else:
//! a fresh engine holds no wall this client is registered in, so there is no
//! wall to aim and no `+ new` to pick, and the engine's own remedy is *a
//! workspace this client founds itself registers it too* (REMOTE §4). One
//! line rather than a two-step because the start already reads one line and
//! a held name between two Enters would be a second state to put down.
