   HolmStone survey — deliberately no web fonts. On a Zanzibar mobile
   connection a font request is 100–300 ms before the first word renders.
   System stack is instant and reads fine.

   High contrast throughout: this form gets filled outdoors, in sunlight,
   on a cheap phone. No light grey on white anywhere.
