# Description of Changes
This pull request updates several development dependencies in
`devTools/package.json` and `devTools/package-lock.json` to resolve a
security vulnerability affecting `js-yaml` versions `<4.1.1`.
The key change is upgrading `js-yaml` from `4.1.0` to the patched
version `4.1.1`, which mitigates a prototype pollution vulnerability
(CVE-2025-64718).
Additional related dependencies were upgraded to ensure compatibility
with the updated toolchain, including `stylelint`,
`@stylistic/stylelint-plugin`, and `stylelint-config-standard`. These
updates were necessary because the older versions required the
vulnerable dependency and blocked Dependabot from applying the patch.
**What was changed**
- Updated `js-yaml` to `4.1.1` (security fix)
- Updated `stylelint`, `@stylistic/stylelint-plugin`,
`stylelint-config-standard`, and several transitive dependencies
- Updated `package-lock.json` to reflect these changes
**Why the change was made**
- To resolve CVE-2025-64718, which allows prototype pollution when
parsing YAML
- To unblock Dependabot updates that were previously incompatible due to
dependency constraints
