/*
 * Mode-based Test Configuration
 *
 * Usage examples:
 *
 * 1. Run only mode:standard tests:
 *    npx playwright test --project="mode:standard*"
 *
 * 2. Run only parallel tests for all modes:
 *    npx playwright test --project="*Parallel"
 *
 * 3. Run a specific mode's sequential tests:
 *    npx playwright test --project="mode:multi-main - Sequential"
 *
 * Test tagging examples:
 *
 * // Runs on all modes
 * test('basic functionality', async ({ page }) => { ... });
 *
 * // Only runs on multi-main mode
 * test('multi-main specific @mode:multi-main', async ({ page }) => { ... });
 *
 * // Only runs on postgres mode, and in sequential execution
 * test('database reset test @mode:postgres @db:reset', async ({ page }) => { ... });
 *
 * // Runs on all modes, but in sequential execution
 * test('another reset test @db:reset', async ({ page }) => { ... });
