Pull Request Overview

This PR fixes performance issues in development mode by forcing emotion to always use "speedy" mode for style insertion. The change addresses sluggish UI behavior in compass-web sync by bypassing emotion's default development mode behavior that uses slower style tag insertion.

Key changes:

• Remove NODE_ENV override in webpack config that forced production mode
• Add a new module to force emotion speedy mode at startup
• Improve error handling in the sync script cleanup process
