Budget Scope
Define limits for JS payload, image weight, font cost, and key web vitals. Different route types should have separate targets.
Team Workflow
- Set baseline metrics per route category
- Gate CI on budget regressions
- Surface performance deltas in pull requests
- Track trend movement per release
Common Pitfalls
Avoid single metric obsession. Balance LCP, INP, and CLS targets with runtime stability and maintainable build strategy.
