 * Peakline unified header styles.
 * Loaded via webapp/templates/_header.html on every page that includes the
 * partial, so the same chrome appears regardless of which other stylesheet
 * the page bundles.
 *
 * Selector names match the legacy markup that lived inline in templates,
 * so existing per-page inline theme-toggle and lang-switcher JS continues
 * to bind to the same DOM (#theme-toggle, .sun-icon, .moon-icon, .pro-icon,
 * .lang-switcher-dropdown, .lang-switcher-btn, .lang-switcher-menu).
