Nearly all front end metaframeworks/starters are like this, which is why I've given up on trying to run them in Docker, because it's just over-complicating the deploy process with no real benefit due to what you mentioned, and I'd rather just use simpler tools like Netlify.

Pretty much. I've been able to use some regex-replacements on the build output in the past with varying luck. But it definitely feels like a hack and can break in weird ways. Another option is building all environments into a single container image and then selecting the right build runtime using an environment variable. This makes the build costlier, even if you can build in parallell, and a bigger image takes longer to distribute into your environment.

At that point dedicated frontend hosting infrastructures like Netlify, Vercel, Cloudflare Pages and others seems like a better choice.
