/* =====================================================================
   LANDING PAGE NAV & HERO STYLES (nav.css)
   ---------------------------------------------------------------------
   Used by `index.html` for the marketing / public landing experience.
   Contains the top navigation bar + responsive mobile menu and the
   initial hero container blocks (.container1, .container2, etc.).

   FUTURE IMPROVEMENTS (OPTIONAL):
     - Extract color palette to CSS variables for theming.
     - Unify button styles with those in login.css or a shared base file.
     - Add prefers-reduced-motion adjustments for hover transitions.
