a76f00a08a feat: implement P2P polling app with Automerge sync
Core functionality using Automerge CRDT for real-time P2P sync:
- Creates or loads a shared document via URL hash
- Syncs over BroadcastChannel (local tabs) and WebSocket (wss://sync.automerge.org)
- Persists state to IndexedDB
- Add poll options with case-insensitive duplicate detection
- Toggle-vote per option, tracked per-document in localStorage
- Options sorted by vote count descending
- 2-minute countdown timer that disables voting on expiry
- Copy-to-clipboard for shareable URL

812098a6bb chore: initialize Vite project with Automerge dependencies
Set up project scaffold for a P2P polling app:
- package.json with @automerge/vanillajs, automerge-repo, vite deps
- vite.config.js with wasm and top-level-await plugins required by Automerge
- pnpm-lock.yaml lockfile
- .gitignore excluding node_modules

# P2P Poll App
A peer-to-peer polling application where users create and vote on polls without any central server. All data syncs directly between browsers using WebRTC and CRDTs.
## Features
- **Real-time P2P sync** — poll options and votes sync instantly across all connected peers via WebRTC
- **Collaborative poll title** — editable title that syncs between all participants
- **One vote per user** — each peer gets a stable ID, enforcing one vote per person per option
- **Vote/Unvote toggle** — change your mind anytime
- **Connection status** — see when you're connected and how many peers are in the room
- **Shareable polls** — share via URL with `?room=your-poll-name`
- **No backend required** — runs entirely in the browser
## Tech Stack
- [Yjs](https://yjs.dev/) — CRDT library for conflict-free shared state
- [y-webrtc](https://github.com/yjs/y-webrtc) — WebRTC provider for peer-to-peer connections
- [Vite](https://vitejs.dev/) — Development server and build tool
- Vanilla JavaScript — no framework dependencies
## Getting Started
```bash
npm install
npm run dev
```
Open `http://localhost:5173/?room=my-poll` in multiple browser tabs to test.
To test across devices on the same network:
```bash
npm run dev -- --host
```
Then open the URL shown in the terminal on other devices.
## How It Works
1. Each browser tab creates a Yjs document and connects to other peers via WebRTC
2. Poll options and votes are stored in Yjs shared data types (Y.Map)
3. Changes propagate automatically to all connected peers using CRDTs
4. A public signaling server handles peer discovery; all poll data flows directly between browsers
