Routing packets, rolling credits, and respawning

A hub reads LIFX button-trigger stats, draws the same frame the Pi Zero shows, and only wakes the Waveshare panel when the counts change.

A Tapo button starts a LIFX scene, spins up a disco ball over infrared, and puts an 80s playlist on a Raspberry Pi.

The gateway already has the port counters. A shim asks it, then answers SNMP so LibreNMS can graph the switches that do not speak it.
