/* ============================================================
   HEADER-SMART — space-saving navigation upgrade
   Susovon Weds Sudipta · Bengali Hindu Wedding Website
   ------------------------------------------------------------
   WHAT THIS DOES
   1. The brand bar (S&S logo + names + date) is NEVER touched —
      it stays visible at all times, exactly as it is.
   2. Tablets & phones (<=1024px): the pill nav ("Home … Venue")
      collapses into a slim gold hamburger button on the right of
      the brand bar. Tapping it opens a glassy dropdown panel.
      Zero nav space is wasted while reading the page.
   3. Desktop (>1024px): the pill nav auto-hides when you scroll
      down and slides back the moment you scroll up (or return to
      the top). One-tap access without losing screen space.

   This file loads LAST so its rules win the cascade.
