/* broadwayinc.com landing page: the page shell only (top bar, the
   "Build With Us" header and the footer). Each product section carries its
   own stylesheet in products/<name>/, scoped under its section class, so
   nothing here styles inside a product section and nothing there leaks out.

   One language with the product sections: neutral ink on white, square
   corners, hairlines, a monospace for the running text, and the soft
   hard-edged offset shadow DDBD uses. Avenir, the logo's face, is kept for
   the brand: the wordmark, the headline and the product names. */
