Blueprints (strips)
There are three types of blueprint, each with a number of predefined instances. Each one requires the client application to display it in a certain specific way:
Standard strips – define a rail that is single height and multi-tile.
Magazine strips – define a rail that is double-height, multi-tile, and can optionally contain hero tiles that span multiple rows.
Promotional strips – designed to highlight featured or time-sensitive content.
