Realtime infrastructure for connected apps, live experiences, connected teams, and your next idea.

Add realtime notifications to this existing project using Pubb.

Read the integration guide first:
https://pubb.io/AGENTS.md
SDK installation directory: https://pubb.io/docs#sdk
Shared protocol and dependency selection: https://pubb.io/AGENTS.md
WebSocket Protocol Reference: https://pubb.io/docs/websocket-protocol

Inspect the project's instructions, languages, runtimes, manifests, lockfiles and code structure. Choose dependencies separately for its client and trusted backend. Select the official Pubb SDK matching each part and follow its documented UPM, Git or local package installation. Verify package names and runtime support; a public GitHub repository does not imply a package registry release. Reuse the project's package manager and authentication. Do not add Node.js or a new backend just to integrate Pubb into another stack.

Connect a client to the public channel "notifications" and publish a sample event from the trusted server. If the project has no backend, implement the subscriber and document the required server publisher. Keep personal or restricted data on authorized private channels.

Use placeholders for the app ID, public app key and app secret, following the guide's environment configuration for this framework. Only the public app key belongs in the client. Keep the app secret server-side; I will add credentials locally.

Add connection cleanup, error handling, reconnect backoff and resubscription. Explain the files you changed, the environment setup and how to verify end-to-end delivery. Only report checks you actually ran.
