//   label      — human-readable name shown in the manager
//   width      — px width of the creative
//   height     — px height of the creative
//   min_screen — minimum viewport width (px) at which this size is shown
//   max_screen — maximum viewport width (px) at which this size is shown
//                (null = no upper limit)
//
// An ad can have multiple sizes. The live page renders ALL size variants
// for each ad and uses CSS media queries to show exactly one at a time.
