Design DNA

Near-black navy with a bright blue announcement bar, light grotesk headlines and a sky-blue second line, mono uppercase buttons. The hero shows a greyscale engraving of Benjamin Franklin on a rocket in clouds above a two-row logo strip. A pinned Build/Test/Deploy/Monitor lifecycle uses dim glowing UI cards. The page switches to pale blue for three framework cards with node diagrams, a case-study carousel and big stats, then returns to navy for a dotted particle funnel CTA and a footer over an outlined giant wordmark.
