/* ============================================================
   Liquid-glass navbar — shared across every page (header-glass.blade.php).
   Loaded after theme-light.css in styles.blade.php, so it wins the
   cascade without touching vendor main.css. Deliberately does NOT reuse
   .header-transparent/.tp-header-* rules from main.css: this navbar is
   always-visible frosted glass (fixed, floating island), not the old
   transparent-over-hero-then-sticky-on-scroll pattern -- that pattern is
   also what made nav text (forced white in main.css) invisible on pages
   with no dark hero directly under the header (login, dashboard, about,
   etc.). Paired with header-glass.js, which only toggles a size/blur
   "condense" class on scroll -- no background swap needed anymore.
