   Shared site header — single source of truth for every page.
   Mirrors index.html exactly: two-row header (info bar + sticky nav bar),
   desktop dropdown for "Каталог", mobile compact/pinned header, mobile
   nav panel. Relies on --ink, --ink-soft, --muted, --blue, --blue-deep,
   --line custom properties already defined by each page's own :root.
