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.
Concentric square and rectangular rings in muted mauve and dusty tan wobble outward from small central nuclei, each ring-cluster set in a grid of nested frames that alternate with thin connecting bars. The motif repeats in a regular, offset rhythm, with rectangular medallions and boxy stacks meeting at the joins to form a dense, rolling lattice.
