What we turn on
Static pages where the data allows it. generateMetadata on every public route. A sitemap from the route table. Images through the framework, not a folder of 4MB PNGs.
What we avoid
Client components for entire pages. Fetching in a loop in a server component. Caching that serves yesterday’s price as today’s.
Preguntas
Pages Router instead?
Only if we are inheriting an app that already lives there. New work is App Router.
