Dates need domain validation
A string schema cannot establish that checkout follows check-in. The handler validates real calendar dates, trip length and guest capacity before changing the quote.

WHAT THIS EXAMPLE TEACHES
Make the price basis visible
The sample quote separates nightly cost and a fixed cleaning fee. A production booking must reprice on the server before confirmation.
COMMON QUESTIONS
Are these live hotel rates?
No. Stays, availability and prices are fictional fixtures, with a fixed cleaning fee of $30.
Does preparing a booking reserve a room?
No. It stages a review in this page. The confirmation only completes a local demo booking.
