⚠ NEVER add commits to this pull request.

🤖 This pull request was automatically created to facilitate human review of @webref/css changes triggered by curated data at fdb36ea.

🧐 Please review the diff below and version numbers. If all looks good, merge this pull request to release the changes to npm.

📦 Latest released @webref/css package was v6.10.3. Merging this pull request will release v6.10.4. Make sure that the bump is the right one for the changes.

✍ If any change needs to be made before release, do not add a commit to this pull request. Changes should rather be handled in a separate pull request and pushed to the main branch. You may leave this pull request open in the meantime, or close it. The pre-release job will automatically update this pull request or create a new one once the updates have made their way to the main branch.

🛈 The actual change introduced by this pull request is a version bump in packages/css/package.json. You do not need to review that change. The bumped version is not the version that will be released when this pull request is merged, but rather the version that will be released next time.
