I want to attach an iCalendar (.ics) file to the reservation confirmation email so that booked dates can be directly imported into a smartphone calendar.

Requirements:

• Format the outgoing email as a multipart/mixed MIME message.
• Dynamically generate an iCalendar (.ics) file containing the booking details (date, selected activity/activities, name).
• Set proper MIME headers (Content-Type: text/calendar, Content-Disposition: attachment; filename="date-event.ics") so smartphones (iOS / Android) and calendar apps present a direct "Add to Calendar" import prompt.
