Built in Lovable: customers text it like they'd text a friend — "Biscuit, corgi, a bit matted, Hyde Park, Wednesday morning?" — and get a confirmed, correctly-sized slot on Rosa's route for that part of town in under a minute. Cancellations self-refill from the waitlist, guests reschedule or cancel without a text, and Rosa's desk (Today board, inbox with auto-replies, Insights with conversion funnel and busy-time heatmap, autopilot log) runs the admin for her. Updates go by email and guest links, so text fees are $0.
