The chat.lotusguild.org nginx config (LXC 106) was edited directly on the box
and never tracked — which is how its CSP drifted (kept a dead Sentry URL and
blocked matrix.org logins). Snapshot it as cinny/nginx.conf (verbatim from prod,
incl. the corrected connect-src that now allows matrix.org/*.matrix.org) and
deploy it via lxc106-cinny.sh: back up the live file, swap, `nginx -t`, and
reload only on success (auto-restore the backup if validation fails, so a bad
config can't take the site down). TLS terminates at the NPM proxy, so this is a
plain HTTP server block with no secrets.
