**issue (bug_risk):** Guard `activeFile` in the clipboard handler to avoid potential runtime errors.
`handleDownload` now guards against a falsy `activeFile`, which confirms it can be unset. The clipboard handler still accesses `activeFile.content` without a check, so it can throw when no file is active. Add a similar guard there or disable the copy action when `!activeFile` to keep behavior safe and consistent.

Code Review
The pull request modifies src/components/ai-elements/custom/code-editor.tsx by updating a useCallback dependency array to include activeFile, ensuring the memoized function re-renders when activeFile changes. Additionally, a null check for activeFile was added at the beginning of the handleDownload function to prevent potential errors.

The handleCopy function should include a null check for activeFile similar to handleDownload. Line 149 shows that activeFile uses a fallback to editorFiles[0], but if editorFiles is empty, activeFile could be undefined, causing a runtime error when accessing activeFile.content.
| await navigator.clipboard.writeText(activeFile.content); | |
| setCopied(true); | |
| setTimeout(() => setCopied(false), 2000); | |
| if (!activeFile) { return; } | |
| await navigator.clipboard.writeText(activeFile.content); | |
| setCopied(true); | |
| setTimeout(() => setCopied(false), 2000); |
