/**
 * Vitest configuration for DataLab-Web.
 *
 * Two test suites live side-by-side:
 *
 * - ``tests/ts/``       → fast unit tests of TypeScript modules that do
 *                         **not** need Pyodide (action registry, menu
 *                         building, theme helpers, trust store, …).
 * - ``tests/pyodide/``  → smoke tests that boot a real Pyodide instance
 *                         under Node and exercise the bridge end-to-end
 *                         (kept opt-in via ``--project pyodide``).
 *
 * The default ``npm test`` only runs the ``ts`` project to keep CI fast.
