A brochure page is a stack of bands, and each one decides its own ground. Everything inside reads the band's tone, so a headline, a checklist or a testimonial picks the right ink on its own. Alternate Page and Soft for the body of a page and save Primary and Inverse for the one band that should stop the scroll. In real use a band runs edge to edge; here each one is held inside the render box.

spacing sets the vertical air: Default for a body band, Hero for the first band under the navigation, Compact for the band that holds the closing callout, and None when the caller sets its own padding, as the ribbon band does. width caps the content column: Narrow suits an FAQ, Prose a long read, and Full lets a marquee ribbon run the whole way across. The render box is narrower than the column caps, so widths only differ here at a wide window.

A band only paints the ground and holds the column. Lay out what goes in it with Side by side for copy beside a picture and Grid for a set of tiles; both read the band's tone like everything else.
