Module style 

ANSI styling primitives and the --ansi / --no-ansi / NO_COLOR resolution chain used by the help renderer and CLI output. Terminal colors and formatting.

Default: auto-detect via stderr TTY + industry-standard env vars (NO_COLOR, FORCE_COLOR). Explicit override via --ansi/--no-ansi flags (set by main before any rendering). Falls back to plain text when piped or redirected.
