Hi Maintainer, I’m a web3 fullstack developer. I’ve reviewed issue #169 and understand the requirements. I’d like to implement this and submit a clean PR.

My approach:

• Build a notifications center with grouped event types.
• Support table invites, friend requests, tournament reminders, and achievement unlocks.
• Add browser notifications when the tab is backgrounded, with permission handling.
• Handle unread/read states and notification updates cleanly.
• Add tests for notification grouping, permissions, and event handling.

Kindly assign this issue to me.
