How can this be modeled with existing blocks or other means?
I want a heading block and a paragraph block visually (and semantically, if possible and necessary) grouped together.
Example:
Circle around the heading block with text "Hairstyle" and a paragraph block below with text "Beautify your hair".
I can use a group block with a heading block and a paragraph block inside – but I find this quite cumbersome and complex. Can I at least make this group-heading-paragraph block structure reusable and lock it somehow so that only the text and its position as a whole can be changed by the editor user?
