 * Serviço photo mosaic ([textual_servico_mosaico]).
 *
 * The band sits at content width between the article and the footer. Vertical
 * spacing belongs to the Elementor container around it, so this file only lays
 * out the tiles.
 *
 * Two shapes stack: a lead block whose arrangement depends on how many of the
 * first three photos exist, and rows of up to three below it. Row tiles take a
 * fixed height rather than an aspect ratio, because a lone trailing photo at
 * 3:2 across the full column would tower over everything above it.
 *
 * The tile widths quoted in inc/servico-mosaico.php assume the single-serviço
 * template's 1260px content column; change them together.

 * or from the row track, and the image simply fills it.
 *
 * The selector carries two classes on purpose: Elementor ships
 * `.elementor img { height: auto }`, which outranks a single class and, on a
 * replaced element, resolves to the photo's intrinsic height instead of
 * stretching between top and bottom — leaving a strip of the tile's
