/*
  Continental Media — global footer styles.
  Namespaced under .cm-footer. Depends on assets/css/tokens.css.
  See footer.html for the full direction-contract comment.

  Contrast (verified, WCAG AA, against --cm-color-bg #0a0b0d):
    - nav/contact links, white at 82% opacity      -> 13.15:1
    - tagline, white at 70% opacity                -> 9.71:1
    - column titles / copyright, white at 50%      -> 5.33:1
    - --cm-blue-500 hover accent (same choice as
      testimonials/case-study's own dark-ground accent) -> 5.11:1
  All comfortably clear of the 4.5:1 floor for normal text.
