/**
 * Vitest configuration for Astro component tests using Container API.
 *
 * This config uses Astro's getViteConfig() which enables proper Astro component
 * rendering via the Container API. Tests use JSDOM for DOM parsing.
 *
 * Note: Only tests that use the Container API pattern should be included here.
 * Other Astro tests that use Web Component classes directly (class X extends HTMLElement)
 * are not compatible with this config as HTMLElement is not defined in Node.js.
 *
 * Run with: npm run test:astro
