With Elementor Pro: Templates → Theme Builder → Archive → Add New. Condition: Post Type Archive → Articles. Add a second condition for Topics archives so they inherit the same design.
Without Elementor Pro: build a Page with slug blog and use one of the post-grid widgets already installed. Essential Addons “Post Grid”, ElementsKit “Post”, Jeg Kit “Post Block” and UAE “Post Layout” are all available. Set the query source to Articles. Pick one and standardise on it.
