Blog proposal: modeling uncertain tool-call outcomes with variants #1467

I'd like to propose a short ReScript v12 blog tutorial on modeling a tool call with variants.

The planned example would distinguish pending, completed, rejected and unresolved outcomes, then handle each case at the UI boundary. A mock worker would make delayed and reordered replies reproducible without a model account. The lab and article are not built yet.

I read the blog-post instructions, the request for maintainer feedback before starting work, and the earlier interop article. The focus would be applying variants to a small, reproducible workflow. Would it fit the blog, and is there an existing article it should build on?
