/* SMX App Shell
 * Shared styles for app-side pages (behind login or contextual tools):
 *   /perfil, /perfil/configuracoes, /certificado, /certificados/*, /simulation/*,
 *   /caso/* (and /en/ equivalents).
 * NOT for landing/marketing pages — those keep their own inline headers.
 *
 * Pairs with /assets/app-header.js which injects the markup.
