A background should sit behind the text, not in place of it. This paragraph lies on the tile at its true scale — if it reads without effort, the tile can go under content.

Each medallion sits within a ring of blobby scrolls and branching shapes, and the repeat falls into an even, rhythmic lattice of diagonal and vertical bands.
