 * Wedding twin. Carried over unchanged from the approved Hilton CONEXION

 * stage with the interface in fixed zones over it: identity, sections and
 * presenting along the top; where you stand at the left; the story at the
 * lower left; detail on demand at the right; the evening's cues along the
 * bottom. Separation is by alignment, then
 * space, then a hairline. One flat plate per region keeps text readable over
 * the room; there are no gradients, shadows or cards inside the plates.
