In a live site, this opens the salon's own booking page ~ their Square Appointments, Vagaro, or Calendly ~ where the client picks a stylist and a time.
Their calendar, their account, their money. AnchorStart just connects the button.
This is a safe demo target. Nothing here charges a card, books a real time, or sends a message. It exists so the link-out on the sample site actually resolves to something honest.
