Two follow-ups to the plate-recess fix:
- Top surface: full-height frame members that pass UNDER the top board
(back panel, bookshelf column dividers, corner posts) had their top face at
unitHeight — coplanar with the top board's top — so they z-fought through it
(the seam on the top). Drop their top 1mm (cappedFrameY); bottoms stay on the
floor so nothing floats.
- Plate width: the previous pass recessed every board's width, which opened a
1mm gap where boards ABUT the side panels (cubby / bookshelf-with-sides).
Width is now recessed only where boards span OVER posts (open-rack /
no-sides bookshelf); abutting boards keep full width and meet the sides
flush. Depth stays recessed everywhere (gap-free, fixes the back-panel fight).
