Give the main idea room
A page does not become clearer by making everything equally large. Choose the first thing a visitor should notice and let nearby spacing reinforce it. The gaps between groups can explain the structure before a person reads a heading.
Empty space can carry the hierarchy.
Use contrast selectively
A quieter section makes a bold one more effective. Vary image scale, alignment and density around the content instead of repeating the same card row. Keep the underlying grid stable enough that the variation feels intentional.
Check the small screen
Space that works on a wide canvas can become an unnecessary scroll on a phone. Reduce gaps in proportion to the content and preserve the relationship between a label, its heading and its action. The hierarchy should survive the change in width.
