/* Galleria Matthews
   Layout: an entrance hall, then five white gallery rooms in historical order,
   each a wall (frames, plaques, wall text) over a strip of oak floor (bench, shell).
   The gallery commits to one visual world, a lit white gallery, so it keeps a
   single light palette in every viewer theme. */
