/* ==========================================================================
   RevealMenu v1.0 — rozsuwane menu mobilne
   Mechanika: panel na stałe leży pod headerem i jest "odsłaniany" animacją
   clip-path (nie przesuwany), na tle frosted-glass backdropu.
   Zero zależności. Klasy stanu nadaje reveal-menu.js.

   KOPIA DOSTOSOWANA DO MILO PARK. Rozniace sie od oryginalu w reveal-menu/:
   1. tokeny w :root maja kolory i wymiary tego serwisu,
   2. breakpoint 979 -> 900 (sekcja 7), zgodnie z reszta CSS-a,
   3. blokada scrolla nie dotyka `body` (sekcja 4) - patrz komentarz tam.
