/*
 * siteHeader.css
 * Site-wide header: government bar, red NOTICE ribbon, and navy navigation
 * bar. Markup is generated by js/siteHeader.js on every page; ribbon movement
 * is driven by js/noticeTicker.js.
 *
 * Look ported from the Webflow home page (gray government bar with the
 * "Here's how you know" panel; navy bar, Montserrat links, Generation /
 * Transmission / Dams & Reservoirs dropdowns, Energy Czar logo left, P3 logo
 * right). Below 992px the links move into a slide-in drawer opened by a
 * hamburger button.
 *
 * Heights are fixed: the dashboard pages size their content to "viewport minus
 * header" through a flex-column body, so a content-driven header height would
 * shift the charts after fonts load.
 *
 * All classes are namespaced site-* so neither the Webflow remote stylesheet
 * (home/search/policy pages) nor Tabler (dashboard pages) restyles them.
