Creator Announcements

Dismissible, customizable announcement banners to user/creator profiles on RoutineHub. These banners would allow authors to directly communicate important updates, news, or messages to visitors of their profile page. Key functionalities include: - Author-created banners: Users can create and display short, prominent announcements on their profile. - Dismissible by visitors: Once read, visitors can dismiss the banner, similar to website banners. - Global toggle for visitors: Users will have an option in their settings to globally disable viewing all author announcement banners. - Per-user toggle for visitors: For more granular control, users will also be able to disable banners from specific authors they follow, even if the global toggle is enabled.
