   RUST · Marketplace / rede de profissionais sob demanda
   Peça da PRÓPRIA RUST → identidade RUST (brand-kit real):
     preto #0A0A0A + laranja oficial #F54D00 chapado, alto contraste,
     industrial/tech. Textura metálica só existiria no logo real — aqui
     o "R" é tratado como bloco sólido, cor chapada (regra da constitution).
   Tipografia: Space Grotesk (display) + Inter (corpo) + JetBrains Mono
     (números do mecanismo) — mesmo par já usado na casa.
   Fundação (reset / .wrap / .btn / --radius / --container) inlinada do
   library/base/tokens.css, convenção da casa (não há @import).
