/**
 * Variant CSS: hero--overlap-card-on-photo
 * Layer 2 — Variants Library (Path B Recipes architecture).
 *
 * Concept: a LARGE dominant photo anchored at the top (full-width, ~16:8),
 * with a WHITE content card overlapping the photo's LOWER edge — lifted onto
 * the white page with a soft elevated shadow + generous padding. Editorial
 * "card-on-image" lift designed to read premium on a white-background page.
 *
 * The photo is a real <img> (NOT a CSS background) so the recipe pipeline can
 * override it by swapping the first <img src>. Cropping is done here via
 * object-fit:cover + aspect-ratio. The card is a plain wp:group (NOT wp:cover).
 *
 * White-bg safety: card uses --background-card with --text-primary inside, so
 * it stays AA-legible both over the photo and grounded on the white page. The
 * card is driven by tokens — light themes get a solid card; should a dark theme
 * adopt this variant, --background-card / --text-primary follow the theme.
 *
 * @package AI_Base_Theme
 * @since 2026-05-29 (Phase 2 Path B — overlap-card-on-photo hero)
