/* paradigmsystems.ro — one quiet light page.
   The first screen: the mark and one sentence in the middle, the sections as small capitals
   at the top, the six things we build at the bottom; hovering one of them turns the middle
   into a slowly turning object made of points. Everything below reads in the same voice:
   lowercase headings, a lot of air, thin rules. Geist everywhere.
   Motion lives in assets/site.js; with JavaScript off or reduced motion, everything is simply there. */
