Sync of the canonical module. The atproto vhost listens on 0.0.0.0 only, so it
never shares an address group with oc.commoninternet.net (which is the default
server on 100.84.190.30:80 and has no auth in front of it). A new
public-default-reject vhost owns the public addresses — return 444 on 80,
ssl_reject_handshake on 443 — so unmatched, absent or spoofed Host headers from
the internet get nothing, now and after any future vhost is added.
The tailnet is untouched: oc.commoninternet.net still serves opencode there.
Verified with tools/check-exposure.sh in the project repo — 9/9 ok.

Sync of the canonical module in the project repo. forceSSL would have bounced
the gateway's plain-HTTP hop back to the gateway; and the oc vhost's explicit
listen on 100.84.190.30:80 was shadowing this vhost on the tailnet, serving the
opencode UI for Host: atproto.commoninternet.net.

Imports the notplants-atproto module: Docker daemon (this host had none), a
systemd unit running the project's docker-compose stack, and an nginx vhost
proxying to it on 127.0.0.1:8731 with ACME and websocket support.
Opens 80/443 publicly. Until now only 22 was open and everything else was
tailnet-only, so this is a real change in exposure — nginx is now reachable
from the internet. The existing oc.commoninternet.net vhost is untouched and
stays bound to the tailscale IP.
nix/atproto-likes.nix is a COPY; the canonical file lives in the project repo
at /srv/project-orchestrator/projects/notplants-atproto/nix/. Pure evaluation
forbids importing an absolute path outside the flake tree, so it has to be
duplicated here — and a new file must be git-added or nix silently ignores it.
ACME currently FAILS: *.commoninternet.net is a wildcard pointing at
143.244.213.108, so the HTTP-01 challenge is answered by that host (500).
nginx serves a self-signed placeholder and starts fine. Fix is an explicit
A record atproto.commoninternet.net -> 168.119.126.100, then
`systemctl start acme-atproto.commoninternet.net.service`.
Applied with nixos-rebuild switch; container healthy, TLS proxy and wss
verified end to end.
