Can someone explain hot storage versus cold storage without the jargon?

Think of hot storage as your working shelf and cold storage as the storage room out back. Hot is where active albums live — it's the tier that runs the AI photo discovery, face matching and guest delivery, so anything you're currently sharing with guests has to sit there. Cold is the archive: your files are safe, you can share them or download them, but no AI runs on them. The clever bit is that cold storage is bundled with your plan rather than sold as a premium extra.
