#Overview

What a command produces, as opposed to what it reports.

Two different things shared one stream: ConsoleDestinationProvider logs through console.log, so alepha --version came back as a timestamped, coloured, two-line log entry — 112 bytes where a script wanted 0.24.0. Worse, its shape followed LOG_FORMAT, an environment variable the script does not control, so a parser written against one format broke under another.

printHelp had already hit this and worked around it by flipping alepha.logger.format to raw and restoring it afterwards — a global mutation whose own comment records the bug it caused ("flipping the format permanently made every later log lose its timestamp and level"). That workaround also cannot fix scripting: changing the format changes how a line looks, not which stream it goes to.

So output is written here, straight to stdout, never through the logger. The logger keeps narrating; this prints results.

Colour is dropped when stdout is not a TTY, which is what makes the output pipeable without the caller stripping escape sequences by hand. NO_COLOR is honoured for the same reason.
