/*
  PulseLens marketing site — paper editorial.

  Same token system as the dashboard (dashboard/app/globals.css): the
  page runs the light "paper" set on :root, and the product demo card
  runs the dark "calm editorial" set scoped under .pl-dark, so the
  landing page shows both faces of the brand. If a token changes in the
  app, change it here too.
