immich-app/immich ? reverse-engineered prompt

Build me a self-hosted photo and video management solution, like my own private Google Photos. It needs a web interface where I can upload, view, and organize everything, and it should also have native mobile apps for iOS and Android.

The main feature for the mobile app is automatic background backup of photos and videos from my phone. The whole system needs to support multiple users, so my family can have their own separate accounts. It should also have sharing features, like creating shared albums and a partner sharing option.

I want it to have smart AI features, too. It should be able to recognize faces and group people together automatically. I also want to be able to search for photos based on their content (like "dogs" or "beach") and view them on a map based on where they were taken. Please set this all up using Docker for easy deployment.
