Reference

App Store screenshot templates as API presets.

Templates are more useful when they are parameterized: copy, captures, device, proof, and background treatment.

Hook	First screenshot promise	role, headline, screenshot

A screenshot template should be a reusable request shape. That makes it editable by humans and agents without opening a design tool.
