/* ==========================================================================
   فهيم — landing page (index.html)
   Layout: a framed column on a dotted canvas, floating pill header, full-screen menu,
   big brand title, pill buttons, tilted stacked cards, chip cloud.
   Motion follows the site rule (components.css): Arabic text never fades, slides or
   clips. Only shapes move — the dot spotlight, marker sweeps, the menu's circle wipe,
   rings, bars, ticks — and the scrolling ribbon carries English tags only.
