/* Features page — the `isFeatures` branch of `design/design_handoff_site/
   SwiftStats Site.dc.html`, every style attribute converted to a class.

   Loaded only by /features. The bar widths at the bottom are the one place a
   percentage from the design becomes a class rather than a value: `style=` is
   forbidden by `style-src 'self'`, so a width is a named class or it is
   nothing. There are five of them and they are all in the design. */
