 * The TRB-01 beside what it is built from. Same arrangement as .device-grid and for
 * the same reason: the picture is first in the source so it leads on a phone, and
 * moves right only once there are two columns. Unlike the device mockup this is an
 * opaque hangar render, so it takes a hairline and a radius rather than a glow.
