 * topbar with a hidden scrollbar, scrolled-off items are invisible —
 * which is how "Help" disappeared from the right edge.
 *
 * This rule shows icons-only between 768-1023px (tooltip via title=)

 * topbar in icon-only mode falls through to overflow-x: auto, but in

     name, not by icon recognition. The lang switcher already keeps
     its "EN" code at this width via a different class (.st-lang-code),

 * and that caused a serious bug — Tailwind's .flex utility outranks
 * `@media (max-width: 767px) .st-nav { display: none }` on specificity, so
 * the mobile drawer never closed and sat on top of the page intercepting
 * all taps. Now layout lives entirely in this .st-nav rule.
 *
 * Default (≥768px): hamburger hidden, nav flows inline.
 * < 768px:           hamburger visible, nav becomes a slide-down drawer.
 *
 * (We considered the CSS-only :target trick but it breaks back/forward
 * navigation; instead a tiny aria-expanded toggle script lives at the
 * bottom of view.php.)

 * The topbar is brand | nav | user-menu | hamburger. Nav stretches to
 * push user-menu and hamburger toward the right edge. On desktop the
 * user dropdown is always top-right regardless of nav-link count. On
 * mobile, nav becomes a drawer (hidden until tapped); user-menu and
 * hamburger remain in the topbar.
 *
 * v13.7.2 fix: dropped overflow-x:auto from the nav. With v13.6.1's
 * label-collapse at 768-1023px (and now 768-1279px), the nav fits
 * comfortably on any desktop width. The overflow-x rule was clipping
 * absolutely-positioned dropdowns (lang switcher menu) which made them
 * appear broken. Without overflow-x, dropdowns extend below the nav as
 * intended.
