   13. SCROLL-IN ANIMATIONS
   ============================================================
   How it works (beginner explanation):
   - Elements start invisible (.fade-in class sets opacity: 0).
   - When JS adds the .visible class, a @keyframes animation plays —
     sliding the element up from 24px below and fading it in.
   - @keyframes is more reliable than CSS transitions for replaying
     animations, because it re-runs every time the class is added.
   ============================================================ */

/* The animation itself: slides up 24px while fading in */
@keyframes fadeSlideIn {
    from { opacity: 0; transform: translateY(24px); }
    to   { opacity: 1; transform: translateY(0); }
}

/* Starting state: invisible. No transform here — the animation handles it. */
.fade-in {
    opacity: 0;
}

/* When .visible is added by JS, play the animation.
   animation-fill-mode: both — holds the "from" state during any delay,
   and holds the "to" state after the animation finishes. */
.fade-in.visible {
    animation: fadeSlideIn 0.5s ease both;
}

/* Stagger delays — each item waits a little longer than the previous.
   Applied via JS by adding delay-1, delay-2, delay-3 classes.
   These only take effect once .visible is also present. */
.fade-in.delay-1.visible { animation-delay: 0.08s; }
.fade-in.delay-2.visible { animation-delay: 0.16s; }
.fade-in.delay-3.visible { animation-delay: 0.24s; }
.fade-in.delay-4.visible { animation-delay: 0.32s; }
.fade-in.delay-5.visible { animation-delay: 0.40s; }
