Struggling to deploy to Mastra Cloud
I've been trying to decouple my Mastra instance from my main Nextjs app, to deploy it to Mastra Cloud. It's been very difficult. I have a number of hacks that I'm not happy with, but right now the one I'm stuck on is this:

I use Zod v4 in the rest of my app, but there are some internal v3 references to Mastra. The Mastra bundler has some settings (that I don't think I can control) that are really causing for a painful experience in managing bundling.
Is there something I'm missing there?
