   /roadmap/ · built on the feature-page kit (main.css, sec-identify.css,
   sec-native.css, feature-page.css). This file adds the one piece the kit
   doesn't have: a vertical timeline. Each stop is date | dot on the rail |
   what lands then. The current stop is the filled mustard dot; the rest are rings.
