Summary

Added major frontend-only platform features (no backend changes) for V3 momentum:

• New shared script: assets/js/platform-v3.js
• Injected on both index.html and settings.html

New capabilities

1. V3 Quick Hub floating button

   • Persistent access point for lightweight power tools.

2. Focus Mode (local)

   • Hides high-distraction chrome (sidebar/auth/settings panel) for cleaner working sessions.
   • Persists in localStorage (360_focus_mode).

3. Command Palette (Ctrl/Cmd+K)

   • Global page jumper to core 360 routes (AI, Weather, Chat, News, etc.).
   • Search/filter actions inline.

4. Quick Notes (local)

   • Fast scratchpad saved to localStorage (360_quick_notes_v1).
   • Export notes to .txt without server usage.

5. Pomodoro Timer (client-side)

   • User-set duration (5–120 min), countdown visible in launcher button.
   • Preferred duration stored locally (360_pomodoro_minutes).

Why this fits request

• Adds as much as possible without backend edits.
• Extends beyond widgets to platform-wide UX/productivity features.
• Works entirely in browser with local persistence.
