   USONIA HOUSE · Catalog of Modern Homes
   Sears Roebuck catalog structure, modernized:
   geometric Futura-style type (Jost), Montserrat masthead,
   Didact Gothic bands + signature rust accent.
   Spacing & proportions follow the golden ratio:
   scale 10 · 16 · 26 · 42 · 68 (each step ~1.618x) and 1.618fr grids.
   Edit tokens below; everything reads them.
