/* ============================================================================
   site.css — shell for the legal pages (privacy policy / terms / game service)

   These pages replaced the old landing page: the site root is now the privacy
   policy, so the shell is deliberately plain: light background, text footer and
   a centred card. The policy wording itself lives in privacy.html /
   service_declare.html and is embedded in a card here (single source).

   The footer used to be an image (static/images/footer.png) that had the old
   contact e-mail printed into it; it is now real text so the address stays
   correct and readable on phones.
