   SmartMuseum — Canonical site header (M2-A3)
   Single source of truth for the header on EVERY front-end view
   (home, page, archive, category, search, 404, single post).
   Enqueued globally; self-contained (does NOT depend on smartmuseum-premium.css,
   which only loads on single posts). Own token namespace: --smh-*.
   RTL via dir="rtl" (set by WordPress/Polylang) + logical properties.

   SOURCE (the Astra header is removed and the N0-C2 .sm-langdd injection was
   deleted), so there is no stray .lang-item in the header to hide. A site-wide
   `li.lang-item{display:none}` would also hide legitimate Polylang lists in the
