Load Testing Script Generator

Generate load tests for this API:

**Endpoints:**
[LIST_ENDPOINTS — e.g.,
  "POST /api/auth/login — authenticate user"
  "GET /api/products?page=1&limit=20 — list products"
  "POST /api/orders — create order"
]

**Target:** [TARGET — e.g., "100 concurrent users, 500 req/sec sustained for 10 minutes"]
**SLA:** [SLA — e.g., "p99 < 200ms, error rate < 0.1%"]

Generate:
1. **k6 test script** — complete script with scenarios and thresholds
2. **Realistic user flow** — simulate actual user journeys (login → browse → purchase)
3. **Ramp-up pattern** — gradual increase to avoid cold-start skew
4. **Data generation** — random but realistic test data for each request
5. **Assertions** — response time percentiles, status codes, error rates
6. **Soak test variant** — long-running test to detect memory leaks
7. **Results interpretation** — how to read the output and identify bottlenecks

Include the complete k6 script ready to run.
