/* ShamashCyber v6 - monochrome.
   Black and white are the only colours in the system. Depth, emphasis and state
   are carried by inversion, borders, opacity and 3D, never by hue.

   Component anatomy follows shadcn/ui (tokens, button, tabs, sheet, accordion,
   sidebar). Depth and motion follow Aceternity UI primitives (container scroll,
   3D card, card spotlight, moving border, card stack, tracing beam, sticky
   scroll reveal, dot background, encrypted text, resizable navbar). Timing is
   GSAP (ScrollTrigger, matchMedia, quickTo) and Anime.js v4 (createTimeline,
   stagger, svg.createDrawable, utils). Nothing else. */
