Consistent styling and customization for Accordion Titles

I want the accordion titles in the Help Center to have consistent styling and the ability to customize their font/style. Currently, the font of accordion elements varies on the same page (e.g., https://community.bezoned.com/help/articles/5518971-faq-bezoned-license-purchase-and-user-management) and there is no way to change the Title style in the editor, only the Body. This causes visual inconsistencies that are difficult to fix without manual HTML cleaning.
