playwright.scalability.config.ts

/**
 * Playwright configuration for scalability tests.
 *
 * Differences from playwright.config.ts:
 *  - NO webServer block — uses the already-running Docker container
 *    (docker-compose up -d must be running before executing these tests)
 *  - testMatch limited to scalability-many-clients.spec.ts
 *  - testIgnore fully removed (not relevant here)
 *  - 1 worker — the spec opens many frames in a single browser page;
 *    additional workers would just multiply Docker load
 *  - Larger timeouts to accommodate 40–100 iframe connections
