A live mood map — pick a feeling or activity, see in real time how many people around the world picked the same.

• WebSocket-backed live counts across ~50 categories (feelings, doing, life)
• City is inferred from request headers; broadcast in the recent-activity feed
• Stateless — everything lives in-memory in the Bun server, resets when the process restarts
• Single static HTML page in public/ connects via /ws

Bun (native Bun.serve + WebSocket). No DB, no framework.

bun install
bun run dev      # watch mode
bun run start    # production

• Listens on PORT env var, defaults to 3110.
• No persistence — counts reset on restart by design.
• Caddyfile and nginx.conf in the repo are the deployed reverse-proxy configs, kept for reference.
