Review Summary

This PR claims to fix a typo but actually introduces one instead. The change adds a double period (..) at the end of line 96, which creates a documentation error rather than correcting one.

Critical Issue

• The production build command line now ends with .. instead of a single ., which is incorrect punctuation

Please correct this to use a single period as shown in the review comment.
