   Self-contained on purpose: this file does NOT depend on bootstrap.min.css
   or leadline.css, so the signed-out landing page can't be broken by changes
   to the in-app design system. Tokens mirror leadline.css by value; all
   classes are prefixed --lp-/.lp- so nothing here can collide with the app.
