vitest.config.ts

/**
 * Vitest configuration for reborn-mark renderer tests.
 *
 * Strategy:
 *   - Inherit Vite's resolve aliases so test imports resolve identically
 *     to dev/build (no parallel alias map to drift). We achieve this by
 *     re-declaring the alias map (the same one in vite.config.js) instead
 *     of mergeConfig — vite.config.js has Tauri/server-port specifics we
 *     don't want in the test runner, and importing the config function
 *     would pull those in.
 *   - jsdom environment for DOM access (Vue + Pinia + Element Plus all
 *     touch document at module load time).
 *   - Globals enabled so test files can use describe/it/expect/vi without
 *     imports — keeps the Phase-4 boilerplate minimal.
 *   - setupFiles installs Tauri API mocks + window.* shim globals before
 *     each test file loads.
