   Arshan – AI / Technology demo (demos/ai-technology/*.html)
   Loads after style.css and before motion.css. Reuses the global header
   (.site-header + [data-ar-nav]), buttons (.btn), motion tokens, reveal and
   accordion systems. Everything demo-specific is scoped to body.ai-page and
   uses the ai- prefix. Form fields keep the shared .ar-field contract that
   main.js ([data-ar-form]) expects.
