Code Review
This pull request optimizes the SpeakerCard component by replacing multiple sequential .find() lookups on the links array with a single .reduce() call to build a mapping object, reducing redundant iterations during rendering. A corresponding learning entry was also added to .jules/bolt.md. Feedback suggests using a fallback array (links || []) before calling .reduce() to prevent potential runtime crashes if the links prop is null or undefined.

To prevent potential runtime crashes (e.g., TypeError: Cannot read properties of undefined (reading 'reduce')) if the links prop is null or undefined from API responses, it is safer to use a fallback array.

| acc[link.linkType] = link.url; | |
| return acc; | |
| }, {} as Record<string, string>); | |
