/*
 * A lightboard is a translucent surface illuminated from behind, used for situations
 * where a shape laid upon the surface needs to be seen with high contrast. In the "old days" of photography
 * photograpers used a lightboard to get a quick view of their slides. The goal is to create a responsive lightbox
 * design, based on flex layout, similar to what is used in Adobe LightRoom to browse images.
