/* PageSight marketing site
   Single stylesheet. No build step.

   Design decisions (locked):
   - One theme: light. Product vignettes sit on dark slate panels as components, not as section theme flips.
   - One accent: terracotta (from the brand mark). Used for the mark, links on hover, and small semantic markers only.
   - Radius system: buttons + inputs 8px, cards + panels 12px, pills full.
   - Type: Geist (variable) for everything; Geist Mono for the few product-surface labels.
   - Motion: transform/opacity only, reveal-on-view via IntersectionObserver, all gated by prefers-reduced-motion.
