Arc Search Summarize Interaction

When the user taps the 'Summarize' button in Arc Search, the active webpage smoothly shrinks and scales down into a floating card, set against a rich, dark magenta gradient background. To indicate the AI is processing, the card performs a playful, organic wiggle animation alongside a 'Summarizing for you...' loading message. Once the summary is ready, the card slides up to the top of the screen, and the AI-generated structured summary slides up from the bottom, revealing beautifully formatted text blocks and icons with a subtle springy settle.
