jest.config.js

/**
 * Jest configuration.
 *
 * Tests are TypeScript and rely on type-aware behaviour (type assertions, enum
 * imports from generated Prisma client), so they are transformed with ts-jest
 * rather than the babel-jest default — babel strips types without checking and
 * cannot parse constructs like `x as any`. tsconfig.test.json supplies the
 * compiler options (it extends the app tsconfig and adds the jest/node types).
