color-thiefvia CDN for processing. - State Management: Use standard JavaScript variables to hold palette state. NO
localStorage,sessionStorage, orcookies. This app must function in a restricted iframe. - Browser Compatibility: Ensure the
CanvasAPI usage is handled safely, as cross-origin images might taint the canvas. UsecrossOrigin = "Anonymous"for the image element. - Responsiveness:
- Mobile: Palette swatches should stack vertically.
- Tablet/Desktop: Palette swatches arranged in a responsive flex or grid layout.
- Interaction: If no file is provided, prompt with a visually appealing call-to-action (custom modal, NOT browser alert) to upload an image.
