🟢danu_quick_compare(person_a, person_b)
Use this when someone wants to know how two people fit astrologically (partners, friends, family, coworkers) and gives birth details for both. Works without a Danu account. Needs each person's birth date and birthplace; birth time is optional. Ask for missing birth details instead of guessing. If the user has linked Danu and the person is already in their Circle, use danu_pair_reading instead.
