/* Visual das telas antes do login (login, convite do beta, demo): o padrao do site umatleta.ia.br (card #975).
 * Cores, raio e fontes vem de tokens.css e fonts.css (copias do repositorio do site); aqui so ficam os componentes,
 * escritos em CSS puro porque essas telas sao HTML do servidor, sem React e sem Tailwind.
 *
 * Tema: o escuro e o padrao, como no site. Quem tem o sistema no claro recebe o claro sem script (o bloco de
 * @media abaixo repete as variaveis de `.light` do tokens.css; um teste confere que as duas listas sao iguais).
 * A classe `light` no <html> tambem liga o claro, como no site.
 *
 * Botoes: `a.b` e `button` sem classe = `<Button variant="marca" size="cta">` do site (pilula na cor da marca);
 * `.sec` = `variant="marcaContorno"`.
