   Quality Thought — AI Forward Deployed Engineer Program

   Palette is sampled from the supplied logo: the orange-red of the mark (#EC3705)
   warming through its inner arm to amber (#FF8C08), against the deep navy of the
   wordmark (#090A4E).

   Navy carries the page. Orange is reserved for things you can act on — the
   primary CTA, the active state, the accent rule under a heading — so it stays
   meaningful instead of decorative. Sections alternate between a light ground
   and a navy ground to give a long page rhythm without extra ornament.

   Deliberately single-theme. This is a brand surface, and a dark-mode inversion
   of a page built around one brand colour reads as a different company. The
   admin panel, where people spend hours, is theme-aware instead.
