    // How to use
    1. Type or paste the position into the box. Any format works, and you don't pick one.
    2. Check the black status chip. It says how the tool read your entry, for example "Read as DMS".
    3. Read any yellow note. It means the tool assumed something, like West. Confirm it with the caller.
    4. Read off whichever format the caller, unit or system needs: DDM, DMS or decimal degrees.
    5. Press Copy next to any format, or press Enter to copy DDM.
    6. If the result turns red, nothing is shown and nothing can be copied. Fix the entry as the message says.
