   SignalMatrix AI — Product vertical page
   Built from the Product.dc.html design export. Foundations
   (colors, type, spacing tokens) come from colors-and-type.css —
   this file only adds page-specific layout and components.

   Accent: Amber/Gold (--amber) is used for all eyebrows, glow
   borders, step indicators, and hover states on this page.
   Pillar colors (green/cyan/purple) appear ONLY in the Pillar
   Cards ("Our Solutions") section — everywhere else uses amber.
