/**
 * The one site header, on every page (written by scripts/build-site-header.py).
 *
 * Its own class names, so no page's stylesheet styles it by accident: several
 * pages still carry rules for the old `.nav-links` and `.bar` headers. Colors
 * come from each page's own palette variables, with the light palette as the
 * fallback.
 *
 * Wide screens get three dropdowns with carets. Below 980px the dropdowns and
 * buttons fold into the Menu button, and assets/site-nav.js shows the same groups
 * as collapsible sections.
