Now I'll remove the button and the showDumpScore state, then always display the dump score chart:

Also need to remove the unused import for useState:

The useState import is still needed for the activeTab state, so no change is required there. Removed the toggle button and showDumpScore state, so the Dump Score History chart now displays immediately when the user clicks the "Dump Score History" tab without requiring an additional button click.

The issue is that the span is rendering on both server and client with different time values. The best fix is to use suppressHydrationWarning on the span since time-based content is expected to differ between renders, and initialize the timeLabel with the calculated value server-side:

Now update the span to use the initial value and suppress hydration warning:

Fixed the hydration mismatch by using useMemo to calculate the initial time label server-side, then updating it in useEffect on the client for accurate current time. Added suppressHydrationWarning to the span since time-based content inherently differs between server and client renders. The component also refreshes the time every minute to keep the display current without full re-renders.

I see the issue - the Sparkline component still has the mounted check that's causing it not to render. The debug logs show hydration mismatches in Sparkline. Let me check and fix the DumpScoreHistory component:

The DumpScoreHistory component looks good. Let me check the coin detail page to see how it's being used:

Good! The coin detail page looks correct - it's importing and using DumpScoreHistory properly. The issue is in the Sparkline component which still has the mounted check preventing it from rendering. Let me fix the Sparkline to not need that check:

Fixed the Sparkline hydration issue by removing the mounted state check that was causing empty SVGs to render on the server. The SVG path calculations are now deterministic and will render identically on both server and client, with suppressHydrationWarning allowing for any minor attribute differences. The Dump Score History graph will now display properly when users click the "Dump Score History" tab on the coin detail page.

Fixed the hydration mismatch in AlertRow by initializing the timeLabel state with initialTimeLabel instead of an empty string. This ensures the server and client render identical text initially (e.g., "5m ago"), preventing the hydration error. The useEffect then updates the time every minute to keep it accurate without causing mismatches.
