# VDS nginx differs from server's in one key way: port 443 is owned
# by an nginx stream block that does SNI-based TCP routing, not by
# http { server {} } blocks. This lets a single host (pubray1.zeroq.su)
# serve both the 3x-ui panel and an Xray REALITY inbound over TLS,
# sharing the same port.
#
# Routing:
# pubray1.zeroq.su → 127.0.0.1:2049 (3x-ui panel; LE cert mounted
# into the container terminates TLS)
# pubrayx1.zeroq.su → 127.0.0.1:15380 (Xray REALITY; Xray sees its
# real configured port 443 via DNAT)
# default → 127.0.0.1:15380 (REALITY fallback for any
# other SNI / IP-direct)
#
# ssl_preread reads SNI from the ClientHello and forwards the rest of
# the TLS stream as-is, so Xray sees a real port-443 connection even
# though podman DNATs it via host:15380.
let
# Goes inside the auto-generated `stream {}` block (services.nginx.streamConfig).
# pubray1.zeroq.su → 3x-ui panel; everything else (including any SNI
# a REALITY client uses, e.g. media.mediavitrina.ru) → Xray.
