/* css/navbar.css — 3Truth "Command Bar" navigation
   Single source of truth for the nav across all pages.
   Self-contained: does not rely on purged Tailwind utilities.
   Loaded AFTER main.css so it wins over legacy .site-nav / .nav-link rules.
   Hooks preserved for JS: .site-nav (+ .is-scrolled via premium.js),
   .nav-link / .nav-active / [aria-current] (nav-state.js),
   #nav-login-btn textContent swap (supabase-config / cinematic),
   #mobile-menu hidden/flex/translate-x-full toggling (animations / cinematic),
   [data-language-switcher] injection (i18n.js). */

/* ---------------------------------------------------------------------------
   Frosted navbar
   Two layers of glass:
   1. .site-nav carries a soft full-width scrim that only appears once the page
      is scrolled, so anything passing under the bar is blurred instead of
      colliding with the links.
   2. .nav-inner (the floating pill) gets a stronger blur + saturation and a
      slightly more transparent base, so the backdrop actually reads as glass
      rather than as a flat dark panel.
   Both degrade to a solid-enough background where backdrop-filter is absent.
