+**C163 — largura das colunas no acervo de falas (2026-09-15):** a tabela "Acervo de falas" ganhou larguras explícitas por coluna (Data 8% · Fase 11% · O que é 37% · Menção ao município 32% · Link 12%) porque o sumário oficial e o trecho de menção são descrições elaboradas; o renderer passou a aceitar `width` por coluna e usa `table-layout: fixed` com `overflow-wrap` quando definido (a URL do Diário quebra dentro da célula). Unit 3117/3117 e `tsc` verdes; PDF de Itamaraju regerado.
