[FEATURE] Custom Gradient Frames: Allow users to create frames with 2-3 custom colors #141
Description
Problem / Motivation
Currently, users can only select from several pre-defined frame themes. This limits creative expression for users who want more personalized options.
Proposed Solution
Add a "Custom Frame" option that enables users to pick 2 or 3 colors to generate their own gradient frame. This would provide infinite creative control and allow for unique, personalized avatar frames.
Alternatives considered
- Continue with only pre-defined themes (less flexible for users)
- Allow only solid color custom frames (less visually interesting than gradients)
Acceptance Criteria
- UI option for users to select either 2 or 3 colors for gradient frame
- Proper rendering of custom gradient frames
- Compatibility with all current avatar frame features
