   Portal v53: authoritative geometry layer

   The portal has evolved through several visual iterations.  Earlier sheets
   intentionally used highly-specific selectors with !important rules.  This
   final layer is deliberately more specific so that classic and modern themes
   share one reliable responsive geometry instead of competing heights,
   overflow modes, and card transforms.
