/* =====================================================================================
   dInventory public landing page - Views/Home/Index.cshtml + Views/Shared/_LandingLayout.cshtml.
   2026-10-14 rewrite (explicit user request: "landing page is broken and has color issues on
   mobile - make it more clean and simple"): fewer sections, one navy accent (the app's own
   primary), white / light-grey sections only, no floating chips, no sticky bar, no animations.
   Fonts: Hind Siliguri (Bangla) + Plus Jakarta Sans (English), loaded in _LandingLayout.
   Every class is prefixed ld- so nothing here leaks into the app's own pages.
