Understanding Phase Kickback in Deutsch-Jozsa

I get the math, but I don't intuitively 'feel' how the oracle bit flips the phase of the control qubit. Can someone explain it like I'm 5?

Why does my GHZ state have such low fidelity?

Running on `ibm_brussels`. The counts for |000> and |111> are high, but I see a lot of noise in between. Is this T1 decoherence or just readout error?
