- UDPSender: single shared asyncio DatagramTransport, start/stop lifecycle, fire-and-forget send() - _NullProtocol: swallows OS send errors (UDP delivery is best-effort for LEDs) - SK6812Device.encode_animation_cmd: replaces b'' stub with real 16-byte 0xAC packet - WS2801Device.encode_animation_cmd: replaces b'' stub with real 16-byte 0xAC packet - Both devices delegate to encode_animation_cmd from lightsync.protocol.animation_cmd
