/**
 * PSAS: Animate-on-scroll + hover helpers (site-wide).
 *
 * Usage: add classes to any block (Advanced → Additional CSS class(es)).
 *
 *   Reveal once when scrolled into view:
 *     psas-anim                     (default effect: fade-up)
 *     psas-anim psas-anim--fade-in
 *     psas-anim psas-anim--fade-up | --fade-down | --slide-left | --slide-right | --zoom-in
 *     + optional  psas-anim--delay-1 … psas-anim--delay-4   (0.15s steps)
 *     + optional  psas-anim--slow | psas-anim--fast
 *
 *   Stagger the direct children of a Columns / Group / List block:
 *     psas-anim-stagger             (children fade up one after another)
 *     psas-anim-stagger psas-anim--zoom-in   (any effect modifier applies to the children)
 *
 *   Hover polish (cards, images, buttons):
 *     psas-hover-lift               (card/tile lifts 4px)
 *     psas-hover-zoom               (on an Image block: photo brightens + soft shadow, no movement)
 *
 * Safety:
 *   - Nothing is hidden unless html.psas-anim-ready is set: by a tiny inline <head> script
 *     (so blocks on screen at load animate without a flash), which removes it again after
 *     3s if psas-anim.js never started. No JS = no hiding; the block editor never hides.
 *   - Visitors with "reduce motion" enabled get no animation at all.
 *   - Only opacity/transform are animated: no layout shift.
