The brief
Design a reading page for an imaginary collection of practical field notes. The article should feel calm on a phone and give a desktop reader a useful overview without an intrusive sidebar.
Design decisions
The headline, summary and content occupy one stable reading column. Small section labels and a simple rule help establish the hierarchy. The supporting panel has a secondary tone, so it does not compete with the first paragraph.
Taking the idea further
An actual website needs approved text, semantic heading structure, link states and a content-editing process. The final layout would be checked with real article lengths, image captions and browser zoom before release.
