   eras.css: the web after 1999, one decade-ish at a time.
   warp.js swaps a class on <body>:
     era-2004   glossy Web 2.0 (gradients, reflections, a "beta" badge)
     era-2010   flat Bootstrap (navbar, jumbotron, three columns)
     era-2016   Material (app bar, hamburger, cards, a pink button)
     era-today  see modern.css
   Same words, same markup. Only the clothes change.
