Explain the Rules of Padel to a Beginner

Someone has roped you into a padel game on Saturday and your only racquet sport is tennis, which turns out to be half-wrong. This explains how the court, the scoring, and the walls differ from what you know, so you walk on confidently and do not slow the group down. For tennis players and total beginners heading to their first padel session.
