badge-to-badge interaction
The README says Down broadcasts the current pattern/palette over ESP-NOW, with nearby badges cascading up to about three hops and rate/interaction safeguards. A five-second Down hold disables wireless until reset or power cycle; no BLE protocol is claimed for the default application.
