/**
 * Variant CSS: gallery--single-full-bleed-overlay
 * Layer 2 (Path B gallery role — count-1 expansion, 2026-06-10).
 *
 * One large photograph running edge to edge of the screen (alignfull), tall like a
 * hero banner, with the kicker + headline + one caption laid CENTERED over a bottom
 * gradient scrim. Reads like a cover/"hero" frame filling the whole section.
 * Unlike single-statement-frame (constrained 16:9 card) and cinematic-letterbox-band
 * (low 21:9, left-aligned strip): this is a tall full-viewport hero crop with a
 * centered bottom overlay. On-photo text sits on a scrim, so it uses --on-dark /
 * #FFFFFF, NOT polarity-aware --ink which would vanish (KI-020). Image src is swapped
 * by the photo system. Element Count [1]. Part of the `gallery` role.
