/* ==========================================================================
   Texium Solutions — Sub-Services Grid widget
   Auto-built from a service page's own child Pages: one vertical card
   per sub-service (icon + arrow row, title, description, decorative
   corner graphic), N per row. Cards cycle through 4 accent colors by
   position (blue/green/purple/orange); the first card can additionally
   show an active/selected appearance in its own accent color.
   Consumes design tokens from theme.css only.
