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.
Blue ground is overlaid with interlocking golden-yellow and orange blobs that form star-like clusters and diamond lattices. Star motifs sit in a grid of blue-and-teal rosettes, while bright yellow rings and paired dots link neighbouring cells, so the repeat reads as a rhythmic, staggered lattice that shifts into diagonal bands across the page.
