1//! TerminalOutput adapter — `UserOutput` port backed by stdout/stderr.
2//!
3//! This is a minimal, dependency-free adapter. The full looprs terminal
4//! output (with colour, sanitization, and machine-log JSON) is implemented
5//! in `looprs::ui`. Use this adapter in contexts where those extras are
6//! not available (e.g. tests, embedded use).
