Actual Behavior

When rendering a tutorial that doesn't include the optional featuredImage or authors fields in its frontmatter, the site crashes with:

The component tries to access .src and .join() on undefined properties without checking if they exist first.

Expected Behavior

Tutorials without optional featuredImage or authors fields should render without errors. The layout should gracefully handle these optional fields being undefined.

Steps to reproduce

1. Create a new tutorial file in en with frontmatter that omits featuredImage and authors:

title: My Tutorial
description: A test tutorial
category: introduction

2. Start the dev server: npm run dev
3. Navigate to /tutorials/my-tutorial/

Expected: Page renders normally Actual: TypeError crash
