Add protection against concurrent booking conflicts when multiple designers try to book the same slot simultaneously.

When someone submits a booking, verify the slot is still available before confirming. If another designer booked it while they were filling out the form, show a clear message explaining the slot was just taken and automatically highlight the next available slot in that session.

Consider adding real-time availability updates so slots that get booked appear as unavailable immediately across all open browsers, reducing the chance of conflicts. The goal is to handle this race condition gracefully without frustrating designers who thought they had secured a slot.

Make the experience feel fair and transparent - if someone loses out on a slot, they should understand why and have an immediate alternative option presented to them.
