// Portal test runner (ADR-120). The `@/*` alias is read from the single
// `tsconfig.json` source of truth via vite-tsconfig-paths (ADR-121) — no
// hand-maintained alias map. `node` stays the global default (ADR-124): the
// pure-function suite from Demand 1/2 runs without a DOM. Component tests opt
// into jsdom per file via the `// @vitest-environment jsdom` docblock.
// No Vitest globals (ADR-123): every test imports `describe`/`it`/`expect`/`vi`
// explicitly; only the jest-dom matchers come from `vitest.setup.ts` (ADR-125),
// so the product `tsconfig`/ESLint config stays untouched.
