Sets: group anything, from anywhere

A Set is a collection that ignores cabinet walls. Items stay exactly where they live; the Set just gathers them — "Aviation" can hold the plane's logbooks, your flight-medical appointment, and fifty photos, each from a different place.

• Pin anything to any Set — an item can be in many Sets at once.
• Lens tabs and View toggles work on a Set page the same way they do on cabinets: filter to Media / Calendar / Tasks, flip between list and gallery. The gallery opens a full-screen viewer that stays inside the Set.
• Smart Sets keep themselves current: give a Set a rule ("every photo in these two cabinets") and matching items flow in automatically. Pin to keep something regardless of the rule; exclude to keep something out permanently.
• AI summary — on your own Sets, one click writes a short overview of what's in there and keeps it honest when the contents change.

One important boundary: putting an item in a Set never changes who can see it. Sets organize; sharing decides visibility — always separately. A Set can be published as a public page, and even then only its publicly-visible members appear.
