/* ============================================================
   MOBILE NAV — M1: full-screen frosted menu, Solutions as its
   own slide-to page (chevron in, back-chevron out). Overlay has
   its own top bar (brand + frosted X); the header brand/burger
   hide underneath while open. Values mirror the reference
   "Mobile Menu Options" M1 spec. Replaces the old right-anchored
   .nav-links dropdown below 941px.
