/* IZZY OS — COMPONENTS: biblioteca visual compartilhada. Sprint Premium UX v1, Etapa 2.
   Primitivos reutilizáveis construídos SOMENTE sobre os tokens --izzy-* (tokens.css).
   Regras:
     • só classes .izzy-* (nenhum seletor de elemento nu) => zero impacto onde não adotado;
     • não define variáveis próprias (não cria um sistema concorrente de tokens);
     • reproduz o visual premium canônico já existente (.rbt / .btn-atualizar / .chip / .pill);
     • classes legadas seguem funcionando; adoção é progressiva, sem big-bang;
     • movimento respeita prefers-reduced-motion (bloco no fim). */
