Example Generator — illustrative example

INPUT
Explain an even integer using examples.

RESULT
Typical: 8. Edge case: 0. Counterexample: 7. Even integers are divisible by two without a remainder.

REVIEW
Examples teach boundaries as well as the main rule. Request a typical case, an edge case and a counterexample, then check that each supports the explanation.

This is a teaching example, not a live execution record.
