Sorry for no responding for a long time.

If you are sure those changes are within your expectations, then run npm test -- -u to update snapshots, for passing CI checks.

Please drop all your unrelated changes and rebase feature to fix ci.

We don't need @typography-title-margin-right and @typography-title-margin-left, drop them and make it hard coded.

[mucluck]

Then it will be impossible to use the margin in the theming. Why do you need to hardcode this? My projects require margin.

[afc163]

I don't see any neccessary of setting margin-left and margin-right to headings, could you point out for me by examples?
