The proxy keeps the person's library in a cache folder (hub-products in its data folder), one pack per
product, served like any other pack: the hub says which revision to load and which catalogs host it, each file
comes from a catalog and is checked against the hub's sha256 (files are kept by hash, so a new revision only
downloads what changed), and adult files are fetched with the hub's access token. Products someone wears in a
room that aren't here yet are fetched too, and put on them when they arrive.
