I've created a loading.tsx file for the /app/coins route to resolve the deployment error. The loading component displays a centered spinner with "Loading..." text that will show while the page is loading and before the useSearchParams hook is initialized. This satisfies Next.js's requirement for suspense boundaries when using search params.

I can see the issue. The Portfolio Overview card only shows when portfolioState && cryptoData.length > 1 (line 747). The condition requires more than one coin to be tracked. Let me check if there's only one coin being tracked:

I found the issue! The Portfolio Overview card only shows when there are more than 1 coin tracked (processedAssets.length > 1 at line 210). If a user has only one coin, portfolioState is set to null (line 223), so the card doesn't render.

The solution is to always show at least the Market Intensity card, even when there's only one coin. Let me fix the layout to handle this better:

I've fixed the Portfolio Overview visibility issue. The problem was that when a user tracks only one coin, portfolioState is null, causing an empty div placeholder to render in the grid. Now the layout intelligently adapts: when there are multiple coins, both the Portfolio Overview and Market Intensity cards display side-by-side in a two-column grid; when there's only one coin, the Market Intensity card displays full-width without the empty placeholder, providing a cleaner single-coin experience.
