/*
 * BACKGROUND TRANSITION TECHNIQUE
 * --------------------------------
 * Each school section uses a ::before pseudo-element
 * with `position: fixed` to create a full-viewport background image.
 * The background starts at `opacity: 0` and transitions to `opacity: 1`
 * when the JavaScript IntersectionObserver adds the `.active-section`
 * class. This avoids `background-attachment: fixed` which causes
 * compositing issues on mobile, and gives a smooth cross-fade effect
 * between section backgrounds as the user scrolls.
 * Note: The Home page uses a native static background to allow natural scrolling.
