/* Fase R4: paleta/estrutura reaproveitadas do artefato de wireframe aprovado
   (ver DECISOES_TECNICAS.md D28) — mesma identidade visual, agora com controles
   de formulário reais em vez de caixas simuladas.
   Paleta de destaque (--annotation) em preto/branco (2026-07-31) — homenagem discreta
   pedida pela usuária, sem símbolo ou referência explícita, só a escolha de cor: preto
   sobre o fundo claro, invertendo para branco sobre o fundo escuro. */
