Deep dive into LLMs by Andrej Karpathy

Now when you switch between tabs, you'll see:

• A smooth color transition for the text
• A smooth animation of the underline indicator appearing/disappearing
• All transitions will take 200ms, which is quick enough to feel responsive but long enough to be noticeable

The animations will be subtle but provide good visual feedback when switching between tabs. Would you like me to adjust the timing or add any other animation effects?
