/* ==========================================================================
   INFRATENSOR DESIGN SYSTEM & STYLE PRIMITIVES (V5: GSAP & LENIS SMOOTH MOTION)
   
   Strict Rules Enforced:
   - Alternating Dark / Light cinematic rhythm (100vh viewport framing)
   - "infratensor" wordmark: lowercase, semi-bold (600), reduced letter-spacing (-0.035em)
   - Filled geometric logo (Group.svg with 3D isometric facets)
   - Positive high-trust statistics (98.4%, 100%, <24h, 1-Click)
   - Sophie Bennett Card Craft: 10px-12px radii, distinct 1px hairline borders
   - ZERO SHADOWS globally (--shadow: none !important)
   - Pure motion play: NO opacity fades for split text (yPercent + scale motion only)
   - Animated left-to-right hairline dividers (scaleX: 0 -> 1)
   - Native Lenis smooth scroll compatibility
