/*
 * Orena Design System — componentes base (Fase 2).
 * Documentação: docs/orena/design-system/05-componentes.md
 *
 * Regras deste arquivo (travadas por teste):
 *   - só classes com prefixo `.o-` — nenhum seletor de elemento global
 *     (button, input, table, *, :root...), para CONVIVER com o CSS atual
 *     das telas sem alterar nada até cada tela migrar por PR próprio;
 *   - só tokens `--orena-*` (orena.tokens.css), nenhum asset externo;
 *   - foco nunca removido sem substituto: todo controle tem :focus-visible.
 *
 * Adoção é opt-in: a tela inclui "orena/_design_system.html" no <head>.
