/**
 * Platform Compatibility Layer
 *
 * Provides universal compatibility for custom UIs across:
 * - MCP Apps Extension (SEP-1865) - Standard ui/initialize protocol
 * - ChatGPT Apps SDK - window.openai API
 * - Claude Artifacts - postMessage with theme class
 *
 * BEAM injects all these APIs so apps built for any platform work without modification.
 *
 * @see https://github.com/modelcontextprotocol/modelcontextprotocol/pull/1865
 * @see https://developers.openai.com/apps-sdk/reference/
 * @see https://www.reidbarber.com/blog/reverse-engineering-claude-artifacts
