What to give it

• Service name and type — web app, API service, mobile app, or combination
• Key user journeys — the 3–5 most important flows users take (e.g. "search → product page → checkout")
• Current baseline metrics — P50/P95/P99 latency, LCP, CLS, INP if available (state "no baseline" if not collected yet)
• Tech stack — frontend framework, backend language/framework, CDN, database
• Deployment environment — cloud provider, region(s), edge/CDN configuration
• Cost constraints — any budget or infrastructure limits that affect headroom
