I still strongly oppose your use of aside there. (And it was indeed that that I was referring to in my original comment here.) Those cards are part of the flow of the document, not tangentially related to the adjacent content.
The 1st `<p>` talks about the movie and the `<aside>` talks about a feature/statistic related to the movie.
In mine, the main content talks about the what the library is and how to use it and `<aside>` is used to call out specific features related to the library.
In either, the "feature" content could be part of the main content or called out separately and both would seem reasonable to me.
Sure, if there was a `<card>` element, that would be a better fit, but the definition of an `<aside>` is broad enough IMO ("indirectly related content") that feature callouts don't seem totally counter to the spirit of the tag.
“Document flow” was perhaps a poor choice of word because of its overloaded meaning. I meant “the flow of content and writing within the document” rather than the layout term.
