    console.log(`Usage: to-words <number> [options]

Options:
  --locale <code>    Locale code (default: auto-detected, falls back to en-IN)
  --currency         Convert as currency amount
  --ordinal          Convert as ordinal (e.g. "Third")
  --detect-locale    Print the auto-detected locale and exit
  -h, --help         Show this help

Examples:
  to-words 12345
  to-words 12345 --locale en-US
  to-words 1234.56 --locale en-US --currency
  to-words 3 --locale en-US --ordinal
  to-words --detect-locale
