### What information was incorrect, unhelpful, or incomplete?

A tiny bit of context.

I'm trying to serve a wasm-compiled app behind an Nginx.
I'm getting the following error in the browser console upon calling the `compileStreaming` method of the `WebAssembly` namespace:
`Failed to load module script: Expected a JavaScript-or-Wasm module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.`
The error is very clear: my Nginx indeed sent the `.wasm` file with a `Content-Type: text/plain`.

*So far so good.*

So, what is/are the corrected/expected MIME type(s) for a `.wasm` file?
I expected to find the answer in MDN, however I simply cannot find it on the Internet at all, and I need this piece of info.

### What did you expect to see?

1. Find explicitly a/the correct MIME type there :
```diff
+ (e.g., bad MIME type instead of [insert it/them here please])
- (e.g., bad MIME type)
```

2. Or in more “general” places, like on the page of MIME types, or pages about using wasm in the browser, etc.

### Do you have any supporting links, references, or citations?

Couldn't find correct the MIME type(s) at all...

### Do you have anything more you want to share?

_No response_
