/* ==========================================================================
   RTFlow — família de autenticação (login, /entrar, conta/*)

   Depende de rt-tokens.css + rt-base.css. Só o que é DESTA família, prefixo
   `auth-`. Zero hex, zero px de fonte: falta token → tokens.css da SPA
   primeiro, depois recopia rt-tokens.css.

   Composição: logo (fora do cartão, sobre --rt-bg) → cartão único de 420px →
   trust line → rodapé. Sem painel, sem animação de entrada: é página que
   pinta uma vez e o melhor "feel" no re-login é instantâneo.
