Layout Must Be a Choice, Not the Default
SHOULD: Break predictable symmetric grids with asymmetry, overlap, negative margins, and varied scale. Feature one dominant element at unexpected scale. Use whitespace asymmetrically to create tension.
Test the layout against the brief — if it is the grid you would produce for any similar page, revise it

Why it matters
The symmetric three-column grid is the layout every generator arrives at, for every brief, which is exactly the test upstream proposes: run a similar prompt and see whether you land in the same place. If you do, the layout was not chosen, it was defaulted into. Asymmetry, overlap, varied scale, and diagonal flow are the usual escapes — but they are means, not the point. The point is that the composition should be traceable to something true about this subject.
