craigk5n/webcalendar — reverse-engineered prompt

Build me a web based calendar app for a small organization or family group. I want people to sign in, see shared calendars in month, week, day, year, and agenda views, and add events with details, categories, repeat schedules, and reminders.

There should be an admin area where I can manage users, groups, permissions, and decide who can view or edit certain calendars or events. It should work for one person too, but also handle an intranet style team calendar. Please include import and export for iCalendar files, email notifications for reminders and event changes, search, public event calendar options, and a mobile friendly layout.

Use PHP with a normal database setup, and make it easy to install through a browser setup wizard. If possible, include Docker setup for local testing. Keep the interface simple and practical, not fancy. Look up current docs online if you need to.
