Last March, at 8:14 in the morning, I stood beside the north gallery and watched the facade change every seven minutes. The bright panels did not disappear when clouds crossed them; they became legible. Every gray joint, recessed window, and narrow shadow gave the surface a measure that sunlight alone could not provide.
A grid is a promise to light
That is the useful lesson for any room made of screens and walls: reserve a plane for shadow before adding another finish. The grid is not decoration or a logo. It is a quiet agreement that gives light somewhere precise to arrive.
