//! CEF Helper Process Entry Point
//!
//! This is the subprocess executable that CEF spawns for renderer, GPU,
//! and other secondary processes. It loads the CEF framework, determines
//! the process type from command-line args, and calls cef_execute_process().

fn main() {
    // On macOS, load the CEF framework. Helper processes use a different
    // relative path than the main process (../../.. vs ../Frameworks).
    #[cfg(target_os = "macos")]
