# Felis login-limbo entrypoint.
#
# Pin Limbo's game port to the pod-facing port the operator contract uses. LOOHP/Limbo
# defaults server-port to 30000, but the Felis operator drives everything — the Service
# Port/TargetPort, the TCP/HTTP readiness probe, the container port and the Velocity
# NetworkPolicy — off a single GamePort const (25565). A backend that bound 30000 would
# be unreachable through that fence. Limbo writes a full server.properties on first run
# and merges any partial we leave in place, so seeding/patching just server-port here is
# enough; the spawn schematic still loads from ./spawn.schem.
#
# Idempotent by design: it runs on every start and rewrites only the server-port line,
# so a persisted world volume that already carries a server.properties keeps all its
# other settings.
