// Two test conventions coexist in this repo:
//   - `test/**/*.test.ts` — pre-existing files using the Node `node:test`
//     runner (run via `node --test test/<file>.test.ts`).
//   - `src/**/__tests__/*.test.ts` — vitest tests for new code.
//
// Scope vitest to `src/**` so it never picks up the node:test files (which
// don't export describe/it/expect and would otherwise fail discovery).
