//   window.go.main.App.*  — the Go methods bound in main.go (each returns a Promise)
//   window.runtime.*      — the Wails runtime API (window title, browser, ...)
// Calling them directly (rather than through the generated frontend/wailsjs
// wrappers) keeps this frontend free of generated files.
//
// Loaded as an ES module (see index.html): strict mode and a private scope
// come for free, and the script runs once the document has been parsed.
