/**
 * Variant CSS: gallery--trio-tall-portrait-row
 *
 * Three slim, tall portrait frames (2:3) in one even row — a strong vertical
 * axis where every photo carries identical weight (hover zoom). Unlike
 * even-trio-row (4:5) and stagger-offset-trio (uneven vertical offsets): here all
 * three stand in a level line but are noticeably TALLER — narrow, poster-like
 * columns. 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.
