/* Shared site chrome for the self-contained wiki bundle.

   Reproduces the main portal header — brand + primary navigation + RU/EN toggle
   — from templates/base.html / static/portal/css/site.css, so /wiki/ and every
   sub-page wear the same look and carry the same menu as the rest of the site.
   The markup is built by site-chrome.js; these rules are namespaced under
   `.zh-chrome-*` (with self-contained colours, not the host page's :root vars)
   so they never clash with each wiki page's own styles. */
