sinmun is a newspaper: ten arrangements of a news list, an article page, categories, authors, tags, comments and a breaking strip. canvas is a shop, and also the most general of the bought designs. linka is a magazine. porto is a corporate site and a business directory. The default is ours, and it is the only one that draws every component the platform has.

Each one says which families of component it can draw and which settings it will ignore, so the panel never offers you a control that would do nothing. If a design has no arrangement for a component, the panel does not offer that component on it — which is the only way to stop a page that answers correctly and shows nothing.

A page holds a component by name, not by a link into the design, so changing a section from one design to another keeps every placement and every setting. What changes is how they are drawn.
