/* ==========================================================================
   Family Photo Archive — Static pages stylesheet
   photoarchive.family

   Styles the public shell (includes/public-header.php / public-footer.php) and
   the three static pages: Privacy, Terms, Contact.

   Design system (spec §2):
     Display  Playfair Display   Body  Roboto
     Palette  sage / olive / gold / cream / taupe
   Signature: the project's matted photo-frame card becomes a "mounted archival
   sheet" here — cream mat, hairline taupe border, a thin gold rule under the
   title, warm soft shadow. Legal prose reads like a document mounted in an album.
