   embed.css — shared chrome for every Linkenite infographic embed.
   Each embed is a standalone page loaded in an iframe inside a blog post, so
   this file is the whole design system for that page. Per-infographic styles
   live in the embed's own <style> block, namespaced.

   Brand tokens are read from the live linkenite.com stylesheet — do not invent
   values, and do not restyle per post.
