How I built it

Goal: let visitors book a session without double-booking, with real calendar blocking and instant payment.

Visitor
  │
  ├─► Frontend (Vercel)
  │     booking form + calendar UI
  │     shows price, validates email/phone
  │
  ├─► Availability check
  │     Edge Function: bookingslots
  │     merges in order:
  │       1) booked sessions from database
  │       2) events from Google Calendar (free/busy)
  │       3) rules → 09:00–20:00 IST, 30-min slots, Thursday off
  │     returns only free slots
  │
  ├─► Booking
  │     Edge Function: booking-create
  │     re-validates + atomic lock
  │     → guarantees no two people grab same slot
  │     → creates PENDING hold (15 min)
  │
  └─► Payment
        Razorpay order → checkout → verify
        PENDING → PAID (or auto-released if not paid)
        paid slots then block future availability

Frontend never holds secrets — all calendar & payment keys stay server-side. Same rules run in frontend & backend so UI and database always agree.

What it handles

• Multi-session picks (1/2/3/6) with live total & 10% discount
• Real Google Calendar blocking — if therapist is busy, slot disappears
• Race-safe writes — two users clicking same slot at same time can't double-book
• 15-minute pending hold — abandoned checkouts free the slot automatically
