/**
 * Initial State and Basic Functionality Tests
 * 
 * Core test suite that validates fundamental application features and initial state handling.
 * These tests run first to ensure basic functionality before more complex tests.
 * 
 * Test Categories:
 * 1. Activity Feed
 *    - Verifies server connectivity
 *    - Tests infinite scroll loading
 *    - Checks initial 10 activities load
 *    - Validates additional activity loading
 * 
 * 2. Discovery Features
 *    - Tests project listing
 *    - Verifies infinite scroll
 *    - Checks project card rendering
 * 
 * 3. Account State
 *    - Validates initial no-ID state
 *    - Tests ID generation flow
 *    - Verifies registration notices
 *    - Checks account detail display
 * 
 * 4. Contact Sharing
 *    - Tests name setting functionality
 *    - Validates clipboard operations
 *    - Checks sharing UI elements
 *    - Verifies alert handling
 * 
 * 5. User Registration
 *    - Tests User 0's ability to register others
 *    - Validates gift recording after registration
 *    - Checks contact deletion
 *    - Verifies deleted contact handling
 * 
 * Key Selectors:
 * - Activity list: 'ul#listLatestActivity li'
 * - Discover list: 'ul#listDiscoverResults li'
 * - Account notices: '#noticeBeforeShare', '#noticeSomeoneMustRegisterYou'
 * - Identity details: '#sectionIdentityDetails code.truncate'
 * 
 * State Verification:
 * - Checks empty ID state
 * - Verifies ID generation
 * - Validates alert presence/dismissal
 * - Confirms navigation state
 * 
 * Alert Handling:
 * - Closes onboarding dialogs
 * - Verifies alert content
 * - Checks alert dismissal
 * - Validates alert transitions
 * 
 * Important Checks:
 * - Server connectivity
 * - Data loading
 * - UI state transitions
 * - Error conditions
 * - Clipboard operations
 * 
 * @example Checking activity feed
 * ```typescript
 * await page.goto('./');
 * await page.getByTestId('closeOnboardingAndFinish').click();
 * await expect(page.locator('ul#listLatestActivity li:nth-child(10)'))
 *   .toBeVisible();
 * ```
