/*
 * Homepage slider: video slides.
 *
 * Complements index.css. index.css has drifted from index.scss and is no longer
 * rebuilt from it, so these rules live in their own file instead of the SCSS.
 *
 * Markup:    resources/views/components/homepage/slider.blade.php
 * Behaviour: public/assets/js/slider-video.js
 *
 * Layouts:
 *   - horizontal video     full-bleed (object-fit: cover) behind the text, all screens
 *   - vertical video only  >= 851px: "card" (blurred image backdrop + 9:16 video on the right)
 *                          <= 850px: full-bleed like the horizontal one
 *   - both videos          horizontal above 550px, vertical (full-bleed) at 550px and below
 * Slides without video keep their original markup and are not affected.
