Can I build my own Calendly with AI?

Build a simple appointment booking app similar to Calendly for one-on-one meetings.

**Objective:** Let visitors book a time slot from your available hours.

**Target user:** A freelancer or consultant who needs a branded booking page.

**Core functionality:**
- Public booking page showing available dates/times
- Visitor selects slot and enters name + email
- Booking confirmation screen
- Simple admin view to see upcoming bookings

**Pages/screens:**
- Public booking page
- Confirmation page
- Admin bookings list

**User flows:**
1. Visitor opens booking page
2. Visitor picks date and time
3. Visitor submits contact details
4. System saves booking and shows confirmation

**UI direction:** Clean, professional, minimal, similar to Calendly's simplicity.

**Data model:**
- Availability rules (days, start/end times, slot duration)
- Bookings: { name, email, datetime, status }

**Authentication:** Optional admin login; public booking requires none.

**APIs/integrations:** Email notifications optional for MVP; calendar sync out of scope for first version.

**Explicit exclusions:** No payments, no team scheduling, no calendar sync in v1.
