/* ==========================================================================
   Miloop AI: factloop-demo.css
   Portfolio case study for factloop-newsroom, plus the live demo widget.
   Consumes the tokens defined in style.css and adds no new ones.

   Two naming styles on purpose, matching how the rest of the site already
   splits: hyphenated block names for the static, hand-written page sections
   (as in style.css), and BEM with is-* state classes for the demo widget,
   whose markup is generated in JS (as in lead-intake.css).
