/* ==========================================================================
   IntegroLabs — Landing Page Styles
   Mobile-first. No build step — plain CSS + a couple of CDN animation
   libraries (GSAP, ScrollTrigger, Lenis), loaded as plain <script> tags in
   index.html. No framework, no npm install required to edit this.

   DESIGN DIRECTION (v2, after feedback):
   - Zero rounded corners anywhere — sharp, editorial, "expensive agency"
     look instead of the generic soft-rounded "AI SaaS template" aesthetic.
   - Oversized display type, hairline borders instead of boxed cards,
     custom cursor, film-grain overlay, scroll-driven motion.
