   The Giant Lantern, rebuilt in code.

   Palette: violet night, aqua lantern glow, magenta ember,
            one accent per product
   Type:    Bricolage Grotesque (display) · Figtree (body)
            Spline Sans Mono (machine voice)
   Motion:  three.js light-field (hero) · GSAP ScrollTrigger scroll
            story · Lenis smooth scroll (fine pointers) ·
            magnetic buttons + cursor (fine pointers)
   Every effect degrades: no JS / no WebGL / reduced motion
   all keep content fully visible.
