WalkthroughAdded error handling to the VideoDemo component with client-side state tracking and conditional rendering. When video loading fails, the component displays a fallback GIF image instead. Added corresponding test coverage for fallback UI rendering and button interaction after failure. Changes

27-51: Conditional rendering implemented correctly with consistent styling.The fallback logic properly switches between video and image based on the error state, maintaining consistent styling and dimensions across both render paths.
Consider these optional defensive enhancements:
- Add error handling for the fallback GIF:
{videoError ? ( <img src="/assets/demo.gif" alt="ArkEnv Demo" width={958} className="block max-h-[600px] sm:max-h-[1000px] object-contain" + onError={(e) => { + // Prevent infinite error loop if GIF also fails + e.currentTarget.style.display = 'none'; + }} />
- Add explicit height to prevent layout shift (matches the 958 width aspect ratio if known):
<img src="/assets/demo.gif" alt="ArkEnv Demo" width={958} + height={539} className="block max-h-[600px] sm:max-h-[1000px] object-contain" />Note: The error state persists for the component's lifetime and doesn't retry, which is appropriate for a demo video component.

217-242: Excellent test coverage for the fallback behavior!This test comprehensively validates the error handling path. It verifies the initial state, simulates the error event, and confirms the complete replacement of the video element with the fallback image including all attributes and styling.
244-261: Good defensive test for post-fallback interaction!This test ensures the button remains functional after the video error occurs, which is crucial for maintaining the user experience when the fallback is triggered.

3-6: Clean state management setup.The useState import and videoError state initialization are correct for React 19. The initial state of
falseappropriately represents the no-error condition.
14-16: Error handler implementation is correct.The handler appropriately updates the error state to trigger the fallback UI rendering.

This is a bandaid solution for #254, but not a true fix that would close the issue. |

Add GIF fallback to VideoDemo on video load error and tests to verify behavior and click-through.
