/* NVO Studio — design system
   ---------------------------------------------------------------------------
   Direction: Frosted Glass — chosen via /ui-ux-pro-max's Glassmorphism style
   match against a deep indigo-navy base (real backdrop-filter blur on every
   card, not flat panels — "modern SaaS/high-end corporate" per the tool's own
   best-for list, which fits an internal creative-production tool). One cool
   blue accent is the sole interactive color; amber stays reserved strictly
   for the product-shot warning, unchanged across every candidate this was
   picked from.
