/* site.css — the shared chrome of the public site.

 * The tokens, the top menu, the buttons and the plan cards. Every page of
 * the site links this file, so the menu on the pricing page cannot drift
 * from the menu on the marketing page — which is exactly what happened when
 * each page carried its own copy of the header.
 *
 * The pages keep their own CSS for their own layouts; only the parts that
 * are shared live here.
