// Hide the extra console window on Windows release builds — this is a
// GUI app, so a GUI-subsystem link keeps the black console (with its
// raw ANSI tracing output) from popping up behind the WebView. Debug
// builds keep the console subsystem so `tracing` logs stay visible
// during development. The Tauri CLI sets this automatically; we build
// the client with plain `cargo build`, so we set it by hand.

//! Entry point for the Kanade Client App.
//!
//! Sprint 8 ships only the Windows skeleton (Tauri 2.x + KLP
//! Named Pipe client + handshake + ping). On non-Windows targets
//! (CI cross-checks, dev curiosity) the binary is a stub that
//! prints + exits — Tauri + the Pipe transport are both
//! Windows-bound for now. Linux UDS support lands in a follow-up
//! PR and will widen the cfg gate.
