Skills are read in parallel, so a full scan of a large repository finishes in seconds.
Lit-metal surfaces, hairlines, grain and quiet motion: the details that make it feel made.
The signature of the brand. A thin layer of CSS classes and hooks on top of Tailwind: buttons cut from graphite and pearl with a silver rim, cards with layered shadows, fading hairlines, film grain, and arrivals that respect reduced-motion settings.
