   Values follow the approved mockup

   The header and footer still come from js/header_footer.js and are
   styled by css/main.css. Everything here is scoped under `.home` /
   `home-*` classes so it does not leak into them. It also undoes the
   globals that base.css and main.css would otherwise apply to the new
   content: html font-size 62.5% and fixed line-height, and the bare
   `p` and `span` rules in main.css.
