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.

/clientapi/admin/backups (owner decision 2026-10-07, approving these endpoints in production): the list with what runs,
the restore waiting and the last restore's report; back up now; delete; a download for the password, through a ticket
good for ten minutes in the link's path, as one tar whose length is known first and which honours Range (BackupTar);
an upload in pieces of at most 32 MB, each at the offset already received or refused with it, so a broken upload
resumes, read into a backup only when it holds nothing but plain files under one backup's folder; and a restore for
the password and the host typed out. Every call checks the administrator against the database. nginx streams downloads
for an hour and takes upload pieces unbuffered, rate-limited.
