Implement STATIC=1 environment variable to enable browser-only deployment without proxy server infrastructure. Uses WS4KP_SERVER_AVAILABLE flag to distinguish between server-backed and static deployments for proper URL rewriting and User-Agent header handling. - Add STATIC env var to skip proxy route registration at startup - Inject WS4KP_SERVER_AVAILABLE flag via EJS template based on STATIC mode - Update fetch.mjs to conditionally send User-Agent headers based on server availability - Update url-rewrite.mjs to skip proxy rewriting when server is unavailable - Use renderIndex helper for consistent template data across dev/prod modes - Improve music playlist logging Benefits of integrated approach: - Single environment variable controls both server and client behavior - Flag injection happens once at render time, not on every request - No runtime HTML string manipulation overhead - Clean separation between server-backed and static deployment logic - Same codebase supports both deployment modes without duplication Static mode (STATIC=1): Direct API calls to external services, no caching Server mode (default): Local proxy with caching and API request observability
