Sequence: How to set equal spacing for actor and database lifelines in v1.2026.3+ ?

Hello,

I have a question about setting equal spacing between lifelines in sequence diagrams using the new CSS style syntax.

Up to v1.2026.2, we could achieve equal spacing between participants using:
skinparam ParticipantPadding 40

In v1.2026.3 and later, we can achieve the same result using:

<style>
sequenceDiagram {
  participant {
    Margin 0 40
  }
}
</style>

Is there a similar way to specify the spacing specifically for other classifiers, such as actor or databaselifelines, to keep them equally spaced?

Thank you for your help and for maintaining this wonderful tool.
