How to load sp components from CDN?

[openscript]

I want to load some components from Spectrum via the proposed CDN. Unfortunately the loaded components aren't optimized for production:

Lit is in dev mode. Not recommended for production! See https://lit.dev/msg/dev-mode for more information.

I've created a minimal reproduction:

How to load spectrum components in production with buildless environment?

The suggested CDN doesn't work well in the country I'm residing in. I need to use jsdelivr. How can I get Spectrum components to work with jsdelivr?

You need to work with jsdeliver and find a way for them to surface export conditions on their ESM output. CDNs like JSPM offer this to ensure the production code is served when desired. In that this is a third party offering, there’s little we can do to support you in this effort.
