/* =====================================================
   THE GROWTH WAY — NAVBAR
   -----------------------------------------------------
   Ek hi navbar, saare pages pe.

   Pehle 4 alag markup patterns the:
     index.html      -> .site-header > .container.navbar > .nav-menu
     about/services  -> .site-header > .container.nav > .desktop + #mobile
     contact/folio   -> .site-header > .navbar > .nav-links
     about1.html     -> .navbar (site-header class hi nahi thi)

   Isliye har page pe navbar alag dikhta tha, aur mobile menu
   sirf kuch pages pe chalta tha.

   Ab sab jagah same markup + yahi file.

   NOTE: saare class names "tgw-nav" se start hote hain.
   Ye jaanbujh kar kiya hai — purani 6 stylesheets me .brand,
   .navbar, .nav-links, .desktop already defined hain. Naye
   naam use karne se koi collision nahi hoga aur purani CSS
   ko chhedne ki zarurat nahi padi.
