somansch/annuals ? reverse-engineered prompt

Build me a Home Assistant integration called Annuals that lets me keep track of birthdays, anniversaries, holidays, and other yearly events in one place.

I want to add events from the Home Assistant settings page, one at a time, and also be able to import a bunch at once from CSV, ICS, vCard, or public holidays. Each event should show the next occurrence, how many days are left, and which birthday or anniversary number it is this year, so I can see things like someone turning 30 without doing the math myself.

Please also make a dashboard card that can show the events as a simple list, a compact one line view, or a timeline, and let it include my existing Home Assistant calendars too. It would be great if I could use the events in automations for reminders and notifications, and have a way to mark important people as VIP. If you need anything from current Home Assistant docs, look it up online.
