## Booking

Sumrall Luminary Advisory Group accepts online bookings. To book an appointment, visit https://sumrallluminaryadvisory.com/?booking=open - this opens the booking widget directly. You can also visit the homepage and wait for the "Book now" widget to appear at the bottom of the page.

Booking steps:
1. Open the booking widget using the link above or via the 'Book now' button on the site.
2. Select a service from the available options.
3. Choose a date and time that works for you.
4. Enter your name, email, and any other required details.
5. Confirm your booking - a confirmation will be sent to your email.

### Deep link to the booking widget

Construct a link to pre-fill any subset of the booking flow:
  https://sumrallluminaryadvisory.com/?booking=open&service={id}&date={YYYY-MM-DD}&slot={UTC-ISO}&firstName=...&email=...

The user lands on the deepest pre-fillable step with all fields filled and clicks
"Confirm booking" to submit. The link never auto-books. Omit any params you
don't have - a service-only link opens step 2; a service+slot link opens step 3.

### Booking discovery API

Use the public read endpoints to inspect services and available times before returning a link.
- OpenAPI spec: https://sumrallluminaryadvisory.com/openapi.json
- GET /api/booking/availability
- GET /api/booking/services
- GET /api/booking/time-slots?date=YYYY-MM-DD&serviceId=N&customerTimezone=America/Los_Angeles

Do not create bookings directly. Return a deep link and let the customer confirm in the widget.
