+/// EF Core's <c>UseInMemoryDatabase(name)</c> returns the same backing
+/// store to every <c>DbContext</c> that asks for it under the same
+/// <paramref name="name"/>, in the same process. That means every
+/// fixture that uses the bare <c>"InMemory"</c> connection string
+/// shares the same in-memory database — which leaks state between
+/// fixtures that are supposed to be independent, and silently makes
+/// tests order-dependent.
+///
+/// The fix is to give each fixture its own suffix. <see cref="For"/>
+/// returns a stable, fixture-scoped connection string. The fixture
+/// stores the suffix in an instance field so successive calls within
+/// the same fixture always resolve to the same database.
