What you can copy from these examples
Each template is a working pattern, not a finished app. It gives you the audience, core pages, data model (D1 or R2), access rules and a testing checklist, so you can paste a complete @Sites prompt instead of describing a vague idea.
Two ways to use one: open a template and copy its full prompt, or open the prompt generator to edit the app type, audience, workflow, storage and access into your own draft.
