Great work on this @ramram-mf! Code looks good, and solves the issue. But I had a couple of thoughts regarding the long-term of this element.

First, I noticed we still have mixed use of Spotlight image and Ideas image, etc. (see screenshot below). If we are moving to Ideas I wonder if we should rename it in full (templates & models too) to avoid confusion with this element in the future.

The second thought I had was if we're adding a cta link text, maybe we just should migrate the blog post and cta fields to just use to the new LinkBlock field (the one @danielfmiranda has been migrating a bunch the past couple sprints). For example, we had a request come in last week to link these sections to a PNI article page, but since these fields are strictly limited to a Blog Page, we weren't able to accommodate the request. If it were a LinkBlock, we'd have a lot more flexibility to do that and also include the "Read More" cta text.

Curious to hear your thoughts!

1. The current text links don't go to the corresponding page for me. It just reloads the homepage.
2. Are you able to make the height of the image the same height as the right column, however long it might get? It's ok if it crops further

@robdivincenzo So, I explored changing the blog field to a LinkBlock streamfield, but that made getting and displaying the author data an inconsistent process, which would not align with the design refresh scope in my opinion. Model and field names are updated, reflecting the new Ideas section naming, but the PR is failing the Wagtail CI actions workflow, stating some error with some non existing residual file from my migration olympics. Any thoughts on how to force the CI workflow to pull the latest branch state?

@ramram-mf The text links seem to be missing on mobile, is that intentional?

Ty for cleaning up the naming and looking into the LinkBlock idea, code LGTM! 🚀
