+# Unified LAN proxy for the tekhnohim Tailscale exit-node egress.
+#
+# One 3proxy instance serves BOTH an HTTP proxy (:3128) and a SOCKS5 proxy
+# (:1080), each chained to the Tailscale userspace SOCKS5 (ts-proxy:1055) so
+# clients exit the internet as the Hetzner exit-node IP (89.167.72.79).
+# TCP only (Tailscale userspace SOCKS5 has no UDP ASSOCIATE -> no QUIC/HTTP3).
+#
+# Access model (LAN free, outside password):
+#   * LAN 192.168.0.0/22  -> authorised by source IP, NO password.
+#   * everyone else       -> must authenticate (external clients arriving via
+#                            the router port-forward keep their public source
+#                            IP, so they fall through to the password rule).
+# The username/password lives in a host-only file (0600, NOT in git), mounted
+# separately and pulled in with the include below - same pattern as ts.env.
