# Seam: SearXNG stack boot-persistence via Quadlet.
#
# The gluetun + searxng + valkey trio runs under systemd as quadlet units so it
# survives a reboot (the podman-compose deployment did not). The crux: searxng
# must reuse gluetun's network namespace (Network=gluetun.container) so its
# outbound search traffic exits the WireGuard tunnel, while still reaching valkey
# by name on the shared searxng network.
