A real one
John & Jane
This is a whole keepsake, built the way anyone builds one — the same studio, the same chapters, the same astronomy. The names are invented so it is safe to hand around; everything else is real, including every sky below, each computed for the night and the city that chapter actually happened in.
The interactive one opens a sign-in screen with the demo credentials already filled in — it is how a keepsake with accounts turned on actually behaves, and it is the only way to see the notes and the sealed chapters working.
7 chapters, 7 skies
Every line below was computed from the date, hour and coordinates that chapter carries — not looked up, and not reused between them. Two chapters on different nights genuinely get different moons.

Yours would work the same way
Building one is free and takes no card — an account, a first chapter, and as long as you like to write the rest. You pay at the end, once there is something worth sending.
