/* Reference projects — rid-energy.uz
 *
 * The same photographic tile as the services wall, with three differences that
 * follow from what these are:
 *
 *   16/9, not 4/3   every one of these is a 1920x1080 render, so a 4/3 frame
 *                   would crop a third of each image away for no reason.
 *   figure/figcaption  the caption is the project's name, which is content,
 *                   not chrome — and the photo viewer reads <figcaption>
 *                   directly, so the name never has to be repeated in a
 *                   data- attribute.
 *   no link         a service card is a lead and goes to the contact form.
 *                   A reference project goes nowhere; it opens in the viewer,
 *                   and lightbox.js supplies the zoom-in cursor itself.
