Your board looks nice, as always.

I was told to avoid 90 degree angles in traces, it was something about
impedance or EMI, IIRC.

You do not expect some EMI problems or high impedance from the 90 degree
cornered angles ?

Report(SelectedNetLengths)  comes to mind (may be, or may be not
implemented yet).
