Template-specific patterns appear only when creating new templates through the site editor, providing starting points for template creation workflows.
The templateTypes argument determines which template creation contexts show these patterns. Archive templates might offer different starting points than page templates.
This specialization helps template creation by providing contextually appropriate starting designs rather than requiring developers to build from scratch every time.
Template-specific patterns bridge the gap between theme-provided templates and completely custom template creation, offering guided starting points for common template needs.
