/**
 * 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`).
 *
 * Tests live next to their subject under `src/` (`foo.ts` + `foo.test.ts`).
 * The renderer SDK is aliased to a hand-written stub at
 * `src/nitro-renderer.mock.ts` so jsdom doesn't try to evaluate Pixi +
 * the full message parser/composer registry at import time.
