/* Header and menu (Raouf 2026-10-14: "like Armadillo, our logo in the middle", "a jaw-dropping menu animation, unique and artful").
   The header is three parts: the menu toggle and quick links on the left, the logo in the middle, visit / phone / scheme on the right.
   The menu is "the rug unrolls": a dark woven panel let down from the top like a rug from its rod, the rolled rug and its fringe
   riding the edge; the links are woven in one by one like weft threads, a gold thread under the one in focus, and on wide screens a
   photo for each link fades in beside the list. Closing rolls it back up. Clip-path and transform only (compositor friendly); reduced
   motion and data-motion="none" get a plain fade; without JavaScript the Menu link opens it through #site-nav:target.
   Research (2026): Codrops clip-path reveals, Awwwards menu overlays, the native focus and Escape rules of a modal. */
