What makes a joint feel right?

I’ve been fiddling with the dovetail on the drawer frame for three days now. It’s not the fit—perfect, even—but the way it clicks when I close it? That’s the thing. Like the wood remembers its own shape. I keep wondering: is that just muscle memory, or is there something in the grain we can’t name? What’s the first thing you noticed when a joint finally felt like it belonged?
