Key Features

Gradient Creation:
- Interactive mesh gradient editor with draggable control points
- Multiple gradient types: Mesh, Linear, Radial, and Conic gradients
- Adjustable mesh complexity (predefined sizes: 2x2, 3x3, 4x4, 5x5, and custom user-defined dimensions)
- Real-time color editing with an intuitive system color picker interface
- Multiple color interpolation methods (IDW, Bilinear, Nearest Neighbor, RBF, Linear RGB, Linear HSV) for smooth or distinct color transitions
- Undo functionality (up to 10 history states) for reverting changes
- Randomize gradient function for quick, serendipitous designs

Customization Options:
- Multiple aspect ratios: Square (1:1), Standard (4:3), Widescreen (16:9), and Phone Story (9:16) formats
- Precise color control (RGB) for each gradient point
- Template library with pre-designed gradient combinations (e.g., Sunset, Ocean, Neon, Forest, Cosmic, Fire, Ice, Aurora)
- Ability to reset to the current template's default state
- Quick action buttons for rapid editing workflow (e.g., add point, remove point, randomize)

Export Capabilities:

- Multiple resolution options: Small, Medium, and Large formats (dynamic, e.g., 1080x1080 up to 4096x4096 for square, and proportionally scaled for other ratios)
- Dynamic resolution scaling based on selected aspect ratio
- Gradient data export as JSON (includes points, mesh size, aspect ratio, interpolation method, gradient type, and export resolution) for sharing configurations
- Copy gradient settings (detailed text summary) to clipboard for easy transfer

User Experience:
- Minimizable controls interface for a distraction-free editing canvas
- Haptic feedback for key interactions (e.g., point selection, adding/removing points, template loading, undo, color changes)
