Unnecessary grey background on logo

I saw that part of the CSS is also used for cases studies (pane-bundle-case-study and CTA's) but couldn't find this anywhere on Drupal.org on the 30 or so pages I checked.

I'm not sure if this pane layout is used in other parts of the site. According to the code it can potentially be used in documentation/guide pages, project release pages and perhaps some other places, but I'm not sure if it's actually being used on those.

I'll let @drumm make the call as he might be more familiar with the places where this is used.

Having said the above, there seems to be an empty grid with that layout on some pages, which shows the grey background cell with nothing in it. The MR would fix that, even though it seems to be empty content in those cases.

See the screenshots:
- Empty block with grey background 1 →
- Empty block with grey background 2 →

Yeah, I visited quite a lot of different page types, but couldn't really find any usage of the same element. But then again, I'm not familiar with all the content and how it's set-up 😉 so I guess someone like @drumm has more knowledge about that.

This is by design, the industry landing pages use it, like https://www.drupal.org/industries/retail → . But that does end up being reused as a generic, sometimes non-ideal, way to put things into 3 columns. We have a couple other options for displaying logos that might be a better fit.

This is probably the best place to track using something else to display those panes.
