Greptile Overview

Greptile Summary

This PR improves the visual design of the error boundary fallback UI that displays when a frontend exception occurs.

Key Changes:

• Replaced collapsible <details> element with always-visible error display
• Added a frown face SVG icon for better visual feedback
• Updated styling to be more responsive using viewport units (vmin, vw)
• Changed backgrounds from solid borders to semi-transparent overlays using color-mix()
• Added hover and active states to the Copy button
• Updated instructional text to suggest refreshing the page

The changes are purely cosmetic and do not modify any error handling logic or component behavior.

Confidence Score: 5/5

• This PR is safe to merge - it only contains cosmetic UI improvements to the error boundary
• The changes are purely visual/styling updates that don't affect error handling logic or component behavior. The implementation uses standard CSS features and the code is clean with no logical issues
• No files require special attention
