   Layout concept: an editorial engineering site. One solid ground,
   one accent, hairline rules instead of cards, text lists instead
   of chips. The only drawn object is the layer stack in the hero,
   plus a thin topographic line field behind it. Everything else is
   typography and spacing. Geist throughout, Geist Mono for labels.
