Technical Notes

• Built-in Win2D effects: Most effects are based on Win2D's built-in Microsoft.Graphics.Canvas.Effects, requiring no additional shader files.
• Custom shaders: The Distort (Ripple) effect uses a custom HLSL pixel shader (.bin file), loaded via ShaderLoader.
• Real-time preview: Effects are previewed on the canvas in real time. Click "Complete" to apply, or "Cancel" to restore.
