The same red / yellow / green outreach form Love on The World teams use. Print a stack, write names on the sidewalk, then log the green lights in Kingdom Base so the 48-hour window can start.
How to use it
Red light: no interest at all — tally it and bless them as they go.
Yellow light: they let you pray, but it did not go further.
Green light: they want follow-up. Write name, number, and one human detail.
