   Globe/crescent-triggered dropdown menus mounted in the header nav (rendered
   by js/site-chrome.js). Placed with navigation so visitors find them where
   they expect: easy to discover, clearly labelled, native language names, and
   a compact dropdown rather than a long row of buttons. The language and theme
   pickers share one look (.chrome-picker) so they read as one control group.
   Uses design tokens so both light and dark follow the palette. */
