Page composition

16:9 at 1280×720 remains the safe canvas. Compose on a 12-column grid with an 8px spacing step so visuals align without manual nudging.

Power BI limitation
Power BI has no responsive canvas on desktop: the page scales to fit. Design one canvas size and use the mobile layout view for phones.
