/* RTS — Rail Trans Service landing
   Layout: dark hero over a construction photo, light about/services, the "railway line" key-projects block
   in the middle (graphite, stations on a drawn track, slide-in panel), contacts, footer.
   Single deliberate look in brand colours (red from the logo, graphite, warm white). */
