	// Uses an internal placeholder so regex patterns below can't re-match masked output.
	// Sort longest-first so a longer secret is masked before a shorter substring of it.

	// to be a secret (e.g. flyctl secrets set). Short values like =debug are left alone.
	sanitized = sanitized.replace(/\b([A-Z][A-Z_0-9]{2,})=([^ \n]{8,})/g, '$1=`***`')

	// Sanitize --token VALUE and --token=VALUE patterns (e.g. vercel --token xxx)
