In the example shown, the adhesive 152 is used to couple the first shield portion 182 within the second pocket 151. The inward facing shield surface 154 of the shield 153 is substantially flush with the inward facing second panel surface 120. Similarly, the inward facing shield surface 154 and the inward facing second panel surface 120 are substantially flush with the inward facing first panel surface 119 of the first panel 114 (see, for example, FIG. 7) when coupled to the first panel 114 as described herein.

To couple the first and second panels 114, 116 together, the panels 114, 116 are slid together in-plane until the alignment dowels 171 enter the dowel bores 168, 170 and the second shield portion 184 is fully received within the pocket 150 of the first panel 114. The interaction between the alignment dowels 171 and the dowel bores 168, 170 may substantially ensure proper and repeatable alignment between the first and second panels 114, 116. Extending the shield 153 between the first and second panels 114, 116 may deter ingress and egress of light between the panels 114, 116. In examples in which the alignment dowels 171 and the dowel bores 168, 170 are not provided, the interaction between the second shield portion 184 and the first pocket 150 substantially ensures proper and repeatable alignment between the first and second panels 114, 116. The magnets 149 of the first panel 114 attract the ferromagnetic shield 153 to further couple the shield 153 to the first panel 114.
