/**
 * PW Before / After Slider — genesis-custom-blocks/pw-before-after (v1)
 *
 * Interactive draggable comparison slider for showing image edits in
 * before/after pairs. Pure CSS layout; the drag/touch interaction lives
 * in /static/js/pw-before-after.js (loaded once per page by the PHP
 * template).
 *
 * Markup contract emitted by block.php:
 *
 *   <figure class="pw-ba-block">
 *     [optional header: eyebrow / title / subtitle]
 *     <div class="pw-ba"
 *          data-before="https://cdn.photoworkout.com/...before.jpg"
 *          data-after="https://cdn.photoworkout.com/...after.jpg"
 *          data-before-label="Before"
 *          data-after-label="After"
 *          aria-label="..."></div>
 *     [optional caption]
 *   </figure>
 *
 * The empty .pw-ba div is hydrated by JS: it inserts the two <img>s,
 * two labels, the divider line and the round grip, then wires up the
 * pointer/touch handlers. aspect-ratio is set from the before-image's
 * naturalWidth/Height after load so the box never collapses.
