/**
 * Variant CSS: gallery--mosaic-wide-top-pair
 *
 * A three-photo mosaic — one wide panoramic frame (16:7) on top across the full
 * width, then two frames side by side below (hover zoom). Unlike the left-led
 * triptych or the even row: this is a two-row, panoramic-on-top / even-below
 * layout. Built as a 2-column grid where the wide tile spans both columns on the
 * first row and the pair takes one column each on the second. Text stays --ink
 * (polarity aware); kicker + the em take --accent; tiles use --decor-radius and
 * images carry --photo-filter. Image src are swapped by the photo system.
 * Dedicated to exactly three photos. Part of the `gallery` role.
