Subject: [PATCH] torna carregamento de imagens "lazy" com regex
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Isto é feito utilizando o comando "sed" com regex no arquivo build.sh
para adicionar a string 'loading="lazy"' nos atributos de cada elemento
"img" no arquivo final HTML.
