/* ==========================================================================
   RTFlow — base do design system para páginas server-rendered (Jinja)

   Companheiro de rt-tokens.css (cópia verbatim de rtflow-ui/src/styles/
   tokens.css, guardada por teste). Aqui vivem: @font-face dos woff2 locais,
   o reset do DS e os primitivos `rt-*` liftados de
   "RTFlow Design System (1)/base/components.css" que as páginas Jinja usam.

   Regras: zero hex, zero px de fonte — tudo lê token. Classe nova com
   prefixo `rt-` só se existir no DS; o que é de UMA família de telas vai
   para o CSS dela (ex.: auth.css).
