Calendly

Build me a personal booking page like Calendly. Requirements: - A public /book page showing my available slots for the next 14 days; visitors pick one, enter name + email + note, and get a confirmation page. - Availability = weekly rules in a config file (e.g. Mon–Fri 10:00–17:00, 30-min slots, 15-min buffer between meetings, my timezone) minus existing bookings, rendered in the visitor's local timezone. - Google Calendar sync via OAuth (credentials in .env): busy events block slots, and confirmed bookings are created in my calendar with the visitor invited and a Google Meet link attached. Warn me in the README: this OAuth app setup is the fiddly part · budget an hour for the Google Cloud console alone. - Email confirmations to both sides via SMTP creds in .env. - Cancel/reschedule links with a signed token in the email. - SQLite storage, one Node process, no accounts, no framework lock-in.
