## Validação de dados nutricionais (2026-09-30)
A exibição e a ordenação de energia priorizam `energy-kcal_100g`; na ausência dele, convertem o campo em kJ para kcal usando `1 kcal = 4,184 kJ`. A página do produto usa a mesma normalização. Zero é preservado como dado válido, e valores ausentes, negativos ou não finitos não entram no cálculo. Produtos sem energia ficam no fim da ordenação nas duas direções. A linha baseada em `salt_100g` é identificada como sal.
Os exemplos de campos vêm da [documentação oficial do Open Food Facts](https://openfoodfacts.github.io/openfoodfacts-server/api/tutorial-off-api/). Valores por 100 g e referências existentes da interface são mantidos; o Nutri-Score continua vindo da API.
Com Node.js 22.7+ (verificado em 24.19.0), `pnpm test` executa 6 regressões offline usando o runner nativo, sem adicionar um framework. `pnpm lint`, `pnpm exec tsc --noEmit` e `pnpm build` completam a validação. O build foi verificado com SQLite temporário, sem conexão com um banco de produção. Next.js e eslint-config-next foram atualizados para 15.5.24.
