Agent Skills: layout

Reworks the structure underneath a UI — spacing scale, visual hierarchy, grid and composition, rhythm, and density — turning monotonous or crowded arrangements into intentional ones. Applies while the composition itself is still wrong, ahead of any detail pass. Use when the user says the layout feels off, every section looks the same, the UI is crowded or too sparse, hierarchy is unclear, or nothing guides the eye. For the last-mile pass on a finished feature, use `polish`.
