 * Register Corp BD — Blog Single Post styles.

/* ---------------------------------------------------------------------
 * Reveal safety net.
 *
 * The shared .rcbd-reveal* classes start at opacity:0 and rely on the
 * home page's IntersectionObserver (threshold 0.15) to add .is-active.
 * A long article card is taller than the viewport, so 15% of it is never
 * visible at once and the reveal never fires — leaving the body blank.
 * On the blog single page we force these elements visible regardless of
 * JS so content is NEVER hidden. Any reveal animation is purely additive.
