/**
 * Test runner config — kept separate from vite.config.mjs because the
 * dev/build config wires up the renderer SDK via filesystem aliases that
 * point at sibling working trees (`../renderer`, `../Nitro_Render_V3`).
 *
 * Test files were originally written against pure modules (helpers,
 * stores) that don't pull in the renderer. We now also support
 * component-level tests by aliasing `@nitrots/nitro-renderer` to a
 * hand-written stub at `tests/mocks/renderer-mock.ts` so jsdom doesn't
 * try to evaluate Pixi + the full message parser/composer registry.
