   ANIMATION RECOMMENDATIONS (for future use)
   ─────────────────────────────────────────────
   When you're ready to add animations with JS or
   a lightweight library, here are the suggestions:

   1. HERO ENTRANCE — Fade + slide-up for title,
      tagline, and CTAs with staggered delay
      (e.g., AOS.js or a 5-line IntersectionObserver).

   2. CATEGORY CARDS — Scroll-triggered fade-in
      from bottom as user scrolls into view.
      Each card gets a small animation-delay offset.

   3. TRUST CARDS — Counter animation for any
      stats you add in future (e.g., "500+ orders").

   4. FAB BUTTON — Pulse/ring animation to draw
      attention. Use CSS @keyframes with
      box-shadow pulsing on a ::before pseudo-element.

   5. HEADER SCROLL EFFECT — Add a JS class on
      scroll to increase backdrop-filter blur and
      add a subtle border or shadow.

   6. CTA SECTION — Typewriter effect on the
      headline using vanilla JS.
