Performance needs ownership
Most sites are fast on launch day and slow six months later. The fix is a budget with clear owners.
Recommended guardrails
- Keep critical route JavaScript intentionally small.
- Use responsive AVIF or WebP images.
- Prefer transform and opacity for motion.
- Delay non-essential third-party scripts.
Make the CMS safe by default
Image pipelines, layout constraints and previews should protect performance automatically.
