1. The specifications

   Exercise 1 · 320 XP · 5 objectives checked by tests

   Bruna has an idea for the winter evenings: story nights. A storyteller, a date, a number of seats, and travelers who sign up. Gorm has written the specifications. Your job is to build the feature, end to end, over the six exercises of this chapter.

5. The night before

   Exercise 5 · 320 XP · 5 objectives checked by tests

   Some guests forget their story night. Bruna wants a reminder to go out the night before, to everyone signed up for the next day's story nights. Gorm will run it every evening, and he is wary: nobody must get two reminders, even if he runs the command twice by mistake.
