Code Review
This pull request updates css-minimizer-webpack-plugin and adds terser-webpack-plugin to resolve a security vulnerability in the transitive dependency serialize-javascript. The changes are correct and effectively mitigate the vulnerability. I have one suggestion to use npm's overrides feature for terser-webpack-plugin for better dependency management clarity and maintainability.

For better maintainability and to more clearly express the intent of overriding a transitive dependency, consider using the overrides field in package.json instead of adding terser-webpack-plugin as a direct dependency. This is the recommended approach for such cases since npm v8.3.0, and it is supported by your project's configured Node.js version (>=22).
You would remove this line and add the following to your package.json:
"overrides": {
"terser-webpack-plugin": "^5.3.17"
}

Closing, apologies for the noise. |

Should be done in #944, thanks anyway. |
