   Presentation layer, second pass. The first read as an editorial document:
   everything divided by rules, every cell the same weight, hierarchy carried
   by whitespace alone. This one carries hierarchy in type weight, surface and
   scale — cards and visual compositions, borders only where they separate
   something from something else.

   Sans is the primary voice, because the content is technical. Serif appears
   at four editorial moments and nowhere else.

   Mobile is designed at the bottom of this file as its own layout, not as the
   desktop grid squeezed into 390px.
