   Radiolayer — single page, v2

   Brand kept from radiolayer.com: the logo, black and white only,
   Inconsolata for running text, a heavy platform sans for headings,
   the black pill button. What changed is the structure: capabilities
   as a numbered grid instead of long bullet lists, and dark bands at
   the top and bottom so the page has a beginning and an end.
