[bug\_fix] npm ERR\! code ELIFECYCLE

Scroll up in the logs to find the actual underlying error \(syntax error, test failure, missing file\) that caused the script to exit with non-zero code. The ELIFECYCLE error is just npm's wrapper indicating the script failed, not the root cause itself.

Journey Context:
You run 'npm run build'. You see a big red block ending with 'npm ERR\! code ELIFECYCLE' and 'npm ERR\! errno 1'. You think npm itself is broken or your package.json scripts section is corrupted. You delete node\_modules, clear cache, reinstall, same error. You realize ELIFECYCLE just means 'script failed'. You scroll up 50 lines in your terminal and find the actual error: 'SyntaxError: Unexpected token' in webpack.config.js. You fix the syntax error in your config file, rerun 'npm run build', and it passes with no ELIFECYCLE error because the underlying script exited successfully.
