/* ===================== PAGE LOADER (shared across all pages) =====================
   Full-screen overlay + spinner shown right before a real page navigation
   (form submit / link click) so the customer isn't staring at a frozen page
   during the brief gap before the next page loads. Self-contained — hardcoded
   colors rather than each page's own CSS variables, same reasoning as
   style/lang-switcher.css (page stylesheets don't share a consistent
   design-token naming scheme). */
