"Assuming the transmitter and receiver were perfectly clocked in unison, what
stops the receiver from tuning in in the middle of a byte, thus getting a
nibble from the current byte and a nibble from the next?"
Nothing. That is a synchronization task your receiver must perform. Assuming
the TX and RX clocks are perfectly synchronized is also an unrealistic
assumption for wireless links. Your receiver needs to perform clock recovery
as well.
