UI.Tee (fnord v0.9.29)

View Source

Optional transcript writer for --tee. When started, every UI output (Logger messages, stdout puts, direct stderr writes) is mirrored to a plain-text file with ANSI escape codes stripped.

When not running, write/1 is a silent no-op, so callers never need to check whether tee mode is active.

Summary
