/*
 * 404 PAGE
 * ========
 * Concept: "Broken type." The number 404 is rendered massive, with each
 * digit slightly displaced and rotated — as if the page literally fell
 * apart. The digits react subtly to mouse movement (parallax), reinforcing
 * the feeling of debris floating in space.
 *
 * Hook: The broken, floating digits + the tone of the copy. It's human,
 * wry, unbothered. Not apologetic. Not cute. Just honest.
 *
 * Why Playfair Display at 900 weight? Because the 404 needs to be
 * MASSIVE and sculptural. At this size and weight, Playfair becomes
 * almost architectural — thick strokes, dramatic contrast. The digits
 * become objects, not just text.
