/* ---------- Sticky wrapper ----------
   FIX: sticky must sit on the OUTERMOST wrapper of the navbar.
   A sticky element can only stick inside its parent. The <nav> sits inside
   <header> (and, on injected pages, inside #navbar-container), and those
   wrappers are exactly as tall as the nav, so the nav had no room to stick.
   Making the wrappers sticky (their parent is <body>) fixes it. */

   The menu has twelve items and needs about 1,590px at full size.
   1600px and wider : full size.
   1366px to 1599px : compact spacing and slightly smaller text, so the whole
                      menu (including FAQs and Contact) fits on laptop screens.
   1365px and below : the menu folds into the toggle button.
   If items are added, check these widths again (the JS uses 1366px too). */
