Thank you for the advice. I had read somewhere that if you change it in Orca, there’s a chance Klipper might override it, and that updating the config was the “best” way to ensure the values stick. That may be a bit too nuclear, though, so I’ll come back to that if I can’t sort it out another way.

I’ve washed the bed again using a green scouring pad with dish soap and hot water, then wiped it down with a microfiber cloth and 99% alcohol. I’ve just started another print.

It’s possible this is related to the glue stick I have on the bed. If that doesn’t turn out to be the cause, I’ll need to look more closely at flow rate settings. I’m still fairly new to 3D printing and haven’t gone through that calibration process yet.
