/* AAS — aasolve.com
   One family, one accent. Light and dark via prefers-color-scheme.
   The page is a motherboard: the hero is a pinned stage where the platform is
   assembled as you scroll, a signal then rides a copper spine down the page and
   powers on each section ("chip"). Scrubbing uses CSS scroll-driven animations;
   site.js provides the same thing through --p / stroke-dashoffset where the
   browser lacks them. Reduced motion: everything shown in its final state. */
