It comes in seconds after I ask.  Oh, well.

That, or an elegantized version thereof, will definitely work.  Dealing
with wood movement is the original reason for frame and panel cabinet
doors.  The long grain top and bottom don't move perceptibly, keeping the
door from being ugly small in the winter, and inoperable in the summer.

As I noted, the stacked ply may not be quite such an issue after all, if
you want to keep that.  It's taken me a while to wrap my head around just
how /small/ and /simple/ the microdesktop really is, with (AFAICT) the
single PCB being held only by the edges of the PCB.  In this case, the
Z-movement won't affect the PCB and components mounted to it, so the only
thing that remains is to leave enough space to allow for possible dry
climate shrinkage.
