   Dark is the default look because the client's own assets are dark-native
   (light-wave artwork on near-black, white wordmark with a blue bolt). A
   light theme stays available through the header toggle.
   One accent (brand blue), one cool navy-tinted neutral family, one radius.
   Motion: scroll-driven animations (view() / scroll() timelines) where the
   browser supports them, IntersectionObserver otherwise, pointer physics for
   buttons and the hero photo, cross-document view transitions between pages.
   Everything collapses under prefers-reduced-motion.
