/* ═══════════════════════════════════════════════════════════════════════
   SITE CHROME — the header bar and footer shared by every page.
   Markup comes from site-chrome.mjs (sentinel blocks vc:nav / vc:footer).

   Self-contained on purpose: pages load main.css, learn.css, the ear,
   library, tools or Andalusian stylesheets, or the player bundle. Every rule
   here is namespaced .vc-* and sets what those files set on bare elements,
   and the legacy bare `footer {…}` rules are scoped to footer:not(.vc-footer).

   The bar is position:fixed with an in-flow .vc-spacer of the same height —
   not sticky: main.css puts overflow-x:hidden on html AND body, which makes
   body a scroll container that never scrolls, and sticky then pins to nothing.
