 - **Vite** - Fast build tool for renderer process
 - **Native Swift** - Mouse button state tracking
 
-## Architecture
-
-The application follows a modular architecture:
-
-- **Main Process** (`src/main/`) - Handles screen capture, mouse tracking, and window management
-- **Renderer Process** (`src/renderer/`) - UI for capture window and studio editor
-- **Processing** (`src/processing/`) - Video processing, cursor rendering, zoom effects, and motion blur
-  - `cursor-utils.ts` - Shared cursor utilities (interpolation, easing, hotspots, click animations)
-  - `smooth-motion.ts` - Spring physics and SmoothDamp algorithms for glide effects
-  - `motion-blur.ts` - Directional motion blur using convolution kernels
-  - `sharp-renderer.ts` - Frame-by-frame video rendering with Sharp
-  - `zoom-tracker.ts` - Zoom region calculation and smoothing
-- **Native Module** (`native/`) - Swift-based mouse button state detection
-
