Add an interactive 3D weather-journey landing page for Abrban at the site root.

Replace the root redirect with a scroll-driven three.js scene that flies from
overcast clouds through rain and a thunderstorm into a clear blue sunny sky,
fronted by Persian/RTL marketing sections. The dashboard at /dashboard is
untouched.
