+# panel-native 7 Days to Die runtime image.
+#
+# Unlike third-party images (vinanrra/LGSM, didstopia, etc.), this image does
+# ONE thing: run a 7DTD dedicated server. Download + validate is handled by
+# the panel's SteamCMD updater sidecar, which writes into the same Docker
+# volume we mount read/write here. No LGSM, no tmux, no GitHub-fetch on
+# start, no backup-before-start "surprises" — just the game.
+#
+# Expected runtime layout inside the container:
+#   /game           — SteamCMD-installed 7DTD binaries (panel volume)
+#   /game-saves     — save + config data (panel volume)
+#   /entrypoint.sh  — this image's entrypoint (renders serverconfig.xml and
+#                     execs the game with stdout/stderr unbuffered)
