Layout

A construction skill. It does ONE thing: decide the container, meaning where content sits, how it groups, how it grows and scrolls, and what the URL and the page metadata carry. It does not style the components inside (that's khe-components), choose type or measure (that's khe-typography), set color or shadow (that's khe-color-and-surface), fix phone browser quirks (that's khe-mobile-native), or stress a screen with worst-case data (that's khe-break-ui).
