As a user, I want some example mash ups to see what I’m getting in to.

This issue has no description.

The issue does not name any files, tests, or entry points. First review the existing Next.js frontend and Flask/SQLAlchemy backend to determine where example mashups would belong, then clarify the required examples and format before implementing them; done means users can view representative mashups and the examples are covered by the relevant project checks.
