/*
  Charlotte's Web Book Trailer: case-study styles.

  Every rule is scoped under .cwbt, the wrapper element that plays the role
  the original page gave to <body>. Nothing here styles html, body or any
  element outside .cwbt, except the opt-in "standalone page shell" at the
  bottom, which only applies when <html> has the class "cwbt-standalone".

  Values are copied unchanged from the original published page.

  Theme: light by default; dark when the visitor's OS prefers dark.
  Like the original, an explicit data-theme="light" | "dark" on <html>
  overrides the OS setting.
