+/**
+ * This is a magic file that allows us to run code in the Figma plugin context
+ * from the iframe. It does this by getting the code as a string, and sending it
+ * to the plugin via postMessage. The plugin then evals the code and sends the
+ * result back to the iframe. There are a few caveats:
+ * 1. The code cannot reference any variables outside of the function. This is
+ *   because the code is stringified and sent to the plugin, and the plugin
+ *   evals it. The plugin has no access to the variables in the iframe.
+ * 2. The return value of the function must be JSON serializable. This is
+ *    because the result is sent back to the iframe via postMessage, which only
+ *    supports JSON.
+ *
+ * You can get around these limitations by passing in the variables you need
+ * as parameters to the function.
+ *
+ * @example
+ * ```ts
+ * const result = await figmaAPI.run((figma, {nodeId}) => {
+ *   return figma.getNodeById(nodeId)?.name;
+ * }, {nodeId: "0:2"});
+ *
+ * console.log(result); // "Page 1"
