🧾 About

Tagline — One sentence describing the app.

2–3 sentences: what it is, what problem it solves, and who it's for.

Example:

Application Name is a real-time collaborative whiteboard for product and design teams. It replaces static slide decks and disconnected docs with a shared visual canvas that updates live for everyone in the room — no refresh needed.

⚙️ How It Works

Describe the core user flow:

User visits → Auth check → Dashboard → Feature A / Feature B → Result

1. Authentication: Users sign in via OAuth or email. Sessions are stored securely as HTTP-only cookies.
2. Data Loading: React Query fetches and caches data from the backend API on mount.
3. State: Local UI state (modals, theme) lives in Zustand. Server state is managed by React Query.
4. Real-time (if applicable): WebSocket connection pushes live updates to all connected clients.

💼 Real-World Use Cases

• Product Teams: Collaborate on feature planning in a shared workspace that keeps everyone on the same page without meetings.
• Freelancers: Present deliverables to clients in a polished, interactive format instead of sending PDFs.
• Educators: Build interactive lesson interfaces that students can use at their own pace on any device.
