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

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
