All done! I've updated the copy, edit, and delete buttons in frontend/src/components/ui/wysiwyg.tsx to use semantic colors: (#1412)

**Changes made:**
- Button backgrounds: `bg-foreground` → `bg-muted`
- Icon colors: `text-background` → `text-muted-foreground`
- Check icon (copied state): `text-green-600` → `text-success`

These semantic colors will now adapt correctly to both light and dark modes, following the established patterns in the codebase.
