Make deliberate structural decisions that improve code maintainability and readability. Consider the appropriate implementation layer, proper encapsulation patterns, and logical organization of code components.

Key principles:

Example of proper encapsulation:

// Instead of:
WebContents.prototype._awaitNextLoad = function (navigationUrl: string) {
  // implementation
}

// Use:
function awaitNextLoad(navigationUrl: string) {
  // implementation
}
// Then call with: return awaitNextLoad.call(this)

This approach reduces code complexity, improves maintainability, and makes the codebase easier to navigate and understand.
