   Perspectives page - the article feed: filter bar + a fixed-height scrolling list of article cards, to the right of
   the illustration. The panel keeps the same height however many posts exist (100+ never lengthen the page); it scrolls
   inside, and js/perspectives-feed.js renders the cards in batches as you reach the end.
   The cards are the published posts of the blog (partials/articles.php).
