   SafeLi — High-End Editorial Landing Page
   Timeless, Dignified, High-Quality Aesthetic (Instrument Serif & Inter)
   Zero Gradients · Architectural Precision · Restrained Monochrome & Copper
   
   Animation philosophy: Emil Kowalski's principles —
   - Strong ease-out curves, never browser defaults
   - Stagger on grouped elements (30–80ms)
   - prefers-reduced-motion: gentler, not zero
   - Hover gated behind @media (hover: hover)
   - UI animations under 300ms, reveals can be longer
   - transform + opacity only — no layout-triggering properties
