/* Dayrail marketing site — shared design system.
   Deliberately single-theme: always white/light, regardless of the
   visitor's system dark-mode setting. color-scheme is pinned to "light"
   (not "light dark") on purpose — the previous file left it as "light
   dark" which tells the browser this page supports both, so native
   scrollbars/inputs could render dark against an intentionally light
   design. */
