/**
 * Variant CSS: gallery--trio-framed-passe-row
 *
 * Three frames (3:4) in one even row, each in a generous passe-partout — a wide
 * card-colour mat around the photo, like a matted print on a gallery wall (hover
 * zoom). Unlike even-trio-row / stagger: the photos do NOT touch the tile edge —
 * a passe-partout border of --background-card surrounds each, giving a museum,
 * finished rhythm. Unlike triptych / podium: zero hierarchy, three equal matted
 * works. The mat is the figure's padding + card bg (no extra DOM); the photo sits
 * inset with a hairline --divider-primary edge. Text stays --ink (polarity aware);
 * kicker + the em take --accent; images carry --photo-filter. Image src are
 * swapped by the photo system. Dedicated to exactly three photos.
 * Part of the `gallery` role.
