/* ============================================================================
   enhance.css — Visual enhancement layer for AEMA_GEOSOORI
   Built entirely on the existing design tokens (--accent, --lime, --bg, etc.)
   defined in main.css. Adds: richer hover/glow states, scroll-reveal
   animation, an image lightbox, button ripple feedback, and an upgraded
   hero slideshow with dots + click-to-enlarge. No existing rule is
   overridden destructively — everything here is additive.
   Respects prefers-reduced-motion (see bottom of file), matching main.css.
