What task are you trying to do?

I want to receive notifications for permission requests, questions from agents, and session status updates without having my UI blocked by in-app Toast popups.

What do you do today?

Currently, notifications appear as Toast popups in the bottom-right corner of the app. These popups:

• Block the send/submit buttons
• Create visual noise when multiple notifications stack
• Mix important (permission requests) with less important (status updates) notifications

What would a good result look like?

Replace in-app Toast notifications with native OS notifications (macOS Notification Center / Windows Notification Area) + Dock/taskbar flash feedback:

• System notifications fire regardless of window focus
• Dock icon bounces once on macOS
• Taskbar button flashes once on Windows
• Click notification → bring window to front + navigate to session
• Fallback to Toast if OS notification permission is denied

Which audience does this matter to most?

Extra context

Design document: docs/superpowers/specs/2026-04-29-notification-system-redesign.md

Key changes:

1. Remove focus check in packages/app/src/entry.tsx and packages/desktop-electron/src/renderer/index.tsx
2. Remove notification-related Toast call in packages/app/src/pages/layout.tsx (line 506)
3. Add flashFrame IPC to preload bridge (packages/desktop-electron/src/preload/index.ts and types.ts)
4. Add flash-frame IPC handler in packages/desktop-electron/src/main/ipc.ts
5. Implement platform-specific flash behavior:
   • macOS: app.dock.bounce()
   • Windows/Linux: win.flashFrame(true) + 1-second timer to win.flashFrame(false)

Edge cases addressed:

• OS notification permission denied → Fallback to Toast
• Multiple rapid notifications → Existing 5-second cooldown
• Multi-window scenario → BrowserWindow.fromWebContents(event.sender)
