I’m confident I can handle this task. I understand the requirement to build the floating admin notification dropdown, maintain unread notifications through context, and update the unread count dynamically when new system alert events arrive. I’ll keep the implementation clean and aligned with the existing dashboard architecture while ensuring the UI updates in real time without unnecessary complexity.

I’d like to work on implementing the notification bell dropdown in the dashboard. I’ll maintain the unread notifications through context and connect it to system alert events so the unread count updates dynamically. I’ll also follow the existing dashboard patterns to keep the implementation clean and consistent.
