Note: for #65 we are going to make the News & Art sections look like the Diversity and Voices sections, so I'm going to add work for #65 in this PR instead of a separate one.

https://github.com/INN/umbrella-borderzine/pull/71/commits/8e339a077ec0ecf41201228b049b836d824f711a recreates the top 4x4 widget area to be 2 separate 1x3 areas for #65, making the first 4 widget areas after the featured area to be the 1x3 layout.

New testing instructions (since all of the widget areas are renamed so their existing widgets will be gone): For each Homepage Middle n 1x3 widget area:

• [ ] Add a Largo recent posts widget
• [ ] Give it a title of the category for this widget area. In order, they should be News, Art & Cultura, Immigration & Fronteras, Voices
  • [ ] Number of posts -> 1
  • [ ] Avoid duplicate posts
  • [ ] Thumbnail image -> Large
  • [ ] Excerpt Display -> Default 2 sentences
  • [ ] Show byline
  • [ ] Hide publish date
  • [ ] Limit to category mentioned above

• [ ] Add a second Largo Recent Posts widget
• [ ] Set title to an empty space
• [ ] Number of posts -> 3
• [ ] Avoid duplicate posts
• [ ] Thumbnail image -> Medium
• [ ] Excerpt Display -> None
• [ ] Show byline
• [ ] Hide publish date
• [ ] Limit to same category as the first widget
