In this package's overrides block, all other overrides are pinned to exact versions, but fast-xml-parser is now a caret range (^5.3.9). This can cause the override target to drift on future installs and makes the lockfile version (currently 5.4.2) harder to reason about. Consider pinning fast-xml-parser to a specific version (e.g., the resolved 5.4.2, or at least an exact 5.3.9) to keep overrides deterministic and consistent with the rest of this file.
