Cosmetic design patterns that are each only used for one functional purpose or a specific type of content.

• box effects (backgrounds, borders, opacity)
• typefaces and font weights/styles
• textual effects (letter-spacing, alignment, indentation, decoration, list-style, color)
• bells & whistles (transformations, overflows, shadows, filters, transitions, icons)

Example: a Pass component. It has the look and feel of a physical paper ticket. It wouldn’t make sense to use this component in any other context besides a conference pass.
