Given a page of the Proofite app (the path from the address bar, like /app/digests, /app/edicola, /app/settings, or a full link), says what that page is, what can be done there and which features live on it, with their state for this person; on a briefing or an inbox it also says which one. Use it when the person asks "what is this?", "what can I do here?" or "where do I find X?" about the screen in front of them. The texts are in Italian, the language the app is written in: say them in the person's language. An unknown path gets the list of the pages that exist.
