/*
 * Balakhah Latest Posts — self-contained, theme-neutral card grid.
 *
 * The plugin renders inside unknown themes, most of which ship a global
 * `img { width: 100%; height: auto }` rule. That rule outranks anything we set
 * without !important and breaks object-fit (media letterboxes, avatars blow up
 * to full width), so every image here is absolutely positioned inside a fixed
 * ratio frame and its box metrics are forced.
