      What is this metric?

      The total gzip-compressed size of the internationalization library bundle. It only includes the provider and content retrieval logic after tree-shaking and minification.

      Why is it important?

      A smaller library size reduces the initial JavaScript payload, leading to faster download and execution times on the client.
