Missing chunks make full page hydration fail

[pi0]

Context: https://github.com/unjs/nitro/issues/2335

I am thinking about what we can do to avoid full-page errors like this. We have SSR content that can show at least static data and we have full links that can work without CSR as fallback when this happens.
