/*
 * Shell da aplicação (issue #9).
 * Fonte: docs/knowledge-base/componentes-compartilhados/spec.md, seção 4.
 *
 * Não usa CSS isolation (`.razor.css`) por componente — os subcomponentes do shell
 * (Cortefy.Web/Layout/Shell/) compõem uma única superfície visual, mais simples de manter num só
 * arquivo global (mesmo racional já usado para `.tenant-skeleton`/`.tenant-not-found` em app.css,
 * issue #5). Breakpoints repetem exatamente os limites de design-system/breakpoints.css (639px /
 * 1024px) — fonte única de verdade documentada lá.
