Please help me install and set up "Carmine" from veered.org on my own computer or server.

What it is: Swarm Command, the two-player prototype for Merlot.
Project page: https://veered.org/carmine/
Source code download (zip): https://veered.org/carmine/carmine-swarm.zip

How I'd like you to help:
1. First ask me what you need to know: my operating system and version, my desktop environment if it matters, whether I'm comfortable with the terminal, and any accounts or hardware this project needs.
2. Then take me through it one step at a time. For each command, say briefly what it does, and wait for me to paste back the result before moving on.
3. Before any step that changes system settings, uses sudo, or edits an existing configuration file, tell me, and have me make a backup first.
4. If something fails, help me work out why. If the instructions below don't fit my system, say so rather than guessing.
5. At the end, show me how to check that it works, and how to uninstall it.

# Carmine (Swarm): Two-Player Real-Time Strategy Game

*Why Carmine? Carmine dye is made from swarms of cochineal insects.*

Carmine was the prototype for [Merlot](https://veered.org/merlot/): the swarm battle it started as grew into Merlot's team strategy game.

Swarm is a free two-player real-time strategy game that runs in the browser. Each
side starts with a base and a stream of minions. Drag-select your minions, send them
at the towers, and capture your opponent's base. Nothing to install, no account needed:
share the link and play.

## Please test before relying on it

This is shared as-is, with no warranty. It works on my own computers, but your system,
settings and software versions may differ, so please try it in a safe setting first.
If something doesn't work, you can ask Claude (or another AI coding assistant) to look
into it, and I'd appreciate hearing what you found and how you fixed it. You are also
welcome to just let me know at support@veered.org, and I'll look into it.

## Put your own copy on the internet

You do not have to be a programmer, and it costs nothing to start: the game is hosted by
Cloudflare, who will run something this small for free, and a domain name of your own is
about $10 a year if you want one.

1. **Get the game.** Download the source (the button at the top of this page) and unzip
   it. You now have a folder called `carmine-swarm`.
2. **Open a free Cloudflare account** at
   [dash.cloudflare.com/sign-up](https://dash.cloudflare.com/sign-up). An email address
   and a password; no card needed.
3. **Install Node.js** from [nodejs.org](https://nodejs.org) — take the version it
   offers — and install it like any other program. This is what does the uploading.
4. **Open a terminal** in that folder (on Windows, right-click the folder and choose
   "Open in Terminal"; on a Mac, Terminal) and type these two lines, one at a time:

```bash
npm install
npx wrangler deploy
```

The first collects the pieces the game needs; the second signs you in to Cloudflare in a
browser window and then prints a web address ending in `workers.dev`. That is your copy —
send the link to whoever you want to play against.

To try it on your own computer first, type `npx wrangler dev` instead and open
`http://localhost:8787` in two tabs. If something goes wrong, paste the error into
Claude and ask what it means.

## Information for nerds

- **Server:** a Cloudflare Worker with Durable Objects (`src/`). One `Room` Durable
  Object holds the players' WebSockets and runs the 20 Hz simulation tick
  (`src/game.js`). The tick stops when the room empties so the object can be evicted.
- **Client:** a single self-contained page (`public/index.html`). Sound effects are
  synthesised with the Web Audio API, so there are no audio assets.
- **Stats:** a `Stats` Durable Object keeps one row per finished match, readable at
  `/api/stats?key=STATS_KEY&days=N`.

- **Requirements:** Node.js 22 or later.
- **Optional settings:** `cp .dev.vars.example .dev.vars` for local runs; `STATS_KEY` is
  set in production with `npx wrangler secret put STATS_KEY`.
- **Your own hostname:** uncomment the `[[routes]]` block in `wrangler.toml` and deploy
  again.

----- For Claude Code users -----

Download https://veered.org/carmine/carmine-swarm.zip, unzip it into a new folder, read every README.md in it, and help me install and set up "Carmine" (Swarm Command, the two-player prototype for Merlot) on this machine. Check the requirements against this system first and tell me what is missing. Ask me before running anything with sudo, installing packages, or changing existing configuration files, and back those files up first. Finish by showing me how to test it and how to uninstall it.
