organize code structure

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:

• Use truly private functions instead of underscore-prefixed “private” methods to avoid abuse: function awaitNextLoad(... instead of WebContents.prototype._awaitNextLoad
• Choose the optimal implementation layer for maintainability - move logic to C++ when it reduces code spread across files and improves efficiency
• Organize tests logically with descriptive names rather than excessive nesting: it('returns image with requested size when both dimensions are bigger', async () => { instead of multiple nested describe blocks
• Prioritize fewer files with clearer responsibilities over scattered implementations

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.
