🧹 [code health improvement] Refactor React keys to use unique string properties instead of array indices in Page1

[sunnylqm]

🎯 What: Replaced array index with feature.title as the React key in Page1 feature mapping.
💡 Why: Using array indices as keys in React is an anti-pattern. Using a unique string (title) improves the code health, prevents rendering bugs on array reordering, and follows React best practices. Also removed the unused index callback parameter to maintain clean code.
✅ Verification: Tested syntax/bundling locally with a lightweight bun build command.
✨ Result: Page1.tsx is cleaner and more robust when mapping the feature components.

📝 Walkthrough

Walkthrough

Updated the features card rendering in Page1.tsx to remove the unused index parameter and change the React key from array index to the feature.title property. This improves reconciliation behavior when the features array is reordered without altering the rendered content or styling.

Poem

🐰 A rabbit rejoiced at the key-naming spree,
No more index chaos in the React tree!
With feature.title as the stable guide,
The DOM elements know where to hide,
Reordering flows with grace and with glee! ✨
