# Share URLs

The source is gzip-compressed and base64url-encoded into the URL.

```text
/r/<payload>   play
/c/<payload>   view source
```

Shared play pages show only the game and its controls. Source pages show only the code. Neither includes the site header, footer, URL field or creation prompt.

## Source

One file: `const game` plus helpers. `GameLib` is provided. Do not call `GameLib.run` or include the engine. No imports, network, storage or DOM access.

## Limits

| Target | Max |
| --- | --- |
| Source | 65,536 bytes |
| After gzip | 3,000 bytes |
| Encoded | 4,000 characters |

Not encrypted: anyone with the URL can read the source.

## Runtime

Runs in a sandboxed Worker. A game that blocks for 5 seconds is stopped.
