Descriptor stack
A descriptor stack is the comma-separated list of visual attributes that makes up an image prompt, ordered from subject through environment, composition, lighting, and style.
Order carries weight: terms nearer the front influence the result more. The conventional sequence is subject, action, environment, composition, lighting, medium and style, then quality modifiers and any model parameters.
