icalendar

Icalendar matters only if the evidence supports a paid workflow around keeping booking availability and appointment flows working, not a list of isolated fixes. The current commercial thesis is: Booking failures directly cost appointments, staff time, and customer trust. The entry wedge is to check booking availability, notifications, payment handoff, and calendar sync before customers hit problems.
