# Batch Regex Fix for Mid-Import Syntax Breaks

When migrations introduce blank lines within multi-line imports (e.g., `import (\n\n` instead of `import (\n`), use a line-based sed/awk fixer instead of single-pass regex. First identify the pattern across all files with grep, then apply a simple line-aware regex that matches `^import (` followed by a blank line, replacing with `import (` on the next non-blank line. Test parse afterward with `python -m py_compile` or equivalent to verify all 995+ files are clean before committing.
