A singleton ServerSettings (title, descriptions, contact, thumbnail, privacy policy, terms, rules, relays, media
overrides, PublishActivity), cached by InstanceSettings and read by the instance API, NodeInfo, the instance actor, the
web pages and the mailer; its defaults are the old literals, so nothing changes until an administrator edits.
/clientapi/admin/settings (and /thumbnail), /announcements, /relays for administrators; /clientapi/moderator/log, the
staff's log (AdminAction, written by domain blocks, backups, settings and the CLI; no IP, never a root paired with its
personas). The Mastodon API's rules, extended description, privacy policy, terms of service, domain blocks (Published,
Obfuscate), announcements (dismiss, reactions, streaming) and activity (only when published). Reports carry rule ids.
Media overrides clamped to hard caps. Relays named by the settings reconcile next to the configured ones.
Verified: interop.sh instance accounts relay with mastodon, relay, aoderelay and mailpit, 119 passed.

Mastodon's streaming API: /api/v1/streaming as a WebSocket (streams
subscribed in the URL or by message) and /api/v1/streaming/{stream} as
server-sent events, with health and the URL advertised. The user stream
tells posts reaching the persona's home (not those an exclusive list keeps
apart, which its list stream tells), notifications, edits and deletions;
public, hashtag and list streams tell what belongs in them. An in-process
hub carries ids only; each connection maps a post or a notification for its
own persona as it sends it, so nothing it may not see, or whose author it
blocked or muted, goes out. A deletion reaches only the streams that showed
the post. The token comes as access_token, header or WebSocket protocol.
