/* site-search.css
   Header site search (blog index). Loaded wherever the .site-search markup
   appears — via the SSI header partial on most pages, or embedded directly
   on self-contained pages. Dark theme, brand tokens from css/ug-brand.css.
   The JS also pulls in /css/skeleton.css for the brief loading state. */
