/* topbar-sitewide.css
   S60 2026-05-05: extracted from default-top.tpl to make it cacheable + non-render-blocking.
   Contains:
   - Bug-1 specificity fix for .topbar .topbar__nav (defeats legacy `#header nav` and any `.show` collision)
   - Mobile hamburger drawer (< 768px) — below the fold, deferred
   - Site-search overlay — only renders on click, deferred
   - Forced-colors a11y patch
   Critical above-the-fold rules (.topbar / .topbar__inner / .topbar__brand* / .topbar__cta /
   .topbar__nav desktop) remain inlined in default-top.tpl for first-paint correctness.
*/

/* === BUG-1 FIX: specificity armor for .topbar__nav ===
   Old `#header nav` rules in master.css / navbar.css use position:absolute + width:100%.
   `#header nav` is (1,0,1). To beat it we need either an ID or another class on top of an
   ID. `#header .topbar__nav` = (1,1,0) wins. Legacy venue.js may toggle a `.show` class
   on nav (do not strip it; included for future-proofing).
