-### Git LF/CRLF configuration
-By default, Git on Windows may convert line endings (LF → CRLF). Our Prettier config enforces LF. To avoid unwanted conversions, run one of the following:
-
-```bash
-git config --system core.autocrlf false  # per-system
-git config --global core.autocrlf false  # per-user
