PR #15721: "feat(server): embed web UI assets in binary and serve locally"
#15721

Why it might be related:

This PR appears to address a very similar feature - embedding and serving web UI assets locally. Both PRs seem focused on enabling offline web static serving capabilities, which is a closely related functionality. You should check if PR #15721 has already been merged or if it's addressing the same use case.

I'd recommend reviewing PR #15721 to confirm whether your current PR (18506) is addressing the same issue or if it's a complementary feature.
