/* chrome.css — the site header, footer, buttons and language toggle.
 *
 * Moved verbatim out of landing.css so EVERY page can wear the same chrome,
 * including the ones built on auth.css (which defines none of these classes).
 * Both stylesheets declare the same custom properties, so this file works on
 * top of either. Edit the header/footer look HERE, nowhere else.
