Would you mind doing some sort of cross-section of the top of the headband? I’m curious as to how the mesh is held inside of the two rails, like is it clamped down on the mesh, or…?

Curious whether this uses “TouchID 1” like the other Macbook Pros, or if we’ve gotten an upgrade to the faster TouchID 2 introduced in the iPhone 6S.

... for example, though it is clear that pressure needs to be applied from all four corners, it would be useful to know if the prying should happen from the sides, or the top and bottoms of the keys.

I unfortunately sloshed some coffee onto my keyboard, first time in twenty years I have screwed up like this. Apple wants $620 for the "repair". Would greatly appreciate a little more information on safely removing and replacing keys.
