- Every packet heard is drawn, by kind in fixed colours: advert, DM,
channel, request, ack, other, sent. One that can't be placed on the map
is a ring at your own position.
- A legend pill at the top counts each kind over the last minute.
- On a map without node markers, a flow brings its own nodes (a dot and
the name), fading with it.
- Copies of one packet (the same packet hash) share one fade, so a path
goes out as a whole, not segment by segment.
- 32 flows kept on ESP32 (12 on nRF).
