//! The page's messages API over a seeded store, in process (no port): `/api/messages` lists the
//! messages between sessions newest first with whom each was shown to, `/api/drones` gives each local
//! drone its unread count, the feed shows a send and a refusal, and `/api/messages/seen` acknowledges
//! what the messages view showed the engineer. Written through msg.rs's own API.
