[abh]

Description

When using the default inline styles for elements, a Content-Security-Policy needs to have "unsafe-inline" allowed.

Describe your ideal solution

Hanko could have an option to accept a nonce to include with the inline styles, I think.

Workarounds or alternatives

Hanko Version

latest

Additional Context

I use https://cdn.jsdelivr.net/npm/@teamhanko/hanko-elements/dist/elements.js which I think is the latest version?
