# Layer 1: System deps — display, VNC, window manager, X11 tools, network
# debug tooling. The network tools (iproute2, net-tools, dnsutils, jq) are
# load-bearing for any agent that needs to introspect ports, sockets, or
# DNS from inside the sandbox. Without them, debugging "is chrome's CDP
# port actually listening?" requires apt-get inside a running container,
# which is slow and bloats the layer.
