   IMPORTANTE: Este archivo NO redefine tokens --lg-*.
   Todos los tokens globales viven en lg-tokens.css (DB-2).
   Las reglas aquí son aditivas o estructurales, no competitivas.

   Migration log:
   - :root legacy (--primary-color, --box-shadow, etc.) → ELIMINADO
   - .pagination rules → ELIMINADAS (delegadas a lg-tokens.css)
   - Referencias a vars legacy → migradas a var(--lg-*)
