CLI Terminal Experience

A terminal UI that reads like Claude Code: mostly grey, a few deliberate accents, one line per fact, animation only while something is actually happening, and a plain-text fallback the moment the output stops being a terminal.

Every rule below is enforceable and testable. Follow them exactly rather than approximating the vibe.

1. The two laws

Subtle by default. Colour marks meaning -- a failure, a value the user will act on -- and nothing else. Labels, units, paths, and chrome are dim; values are plain. A full screen of output should read as mostly grey with a handful of accents, never as a colour test page. If you cannot say what a colour means, remove it.
