- keep third-party scripts minimal
- split heavy components
Content strategy
- lead with lightweight hero sections
- defer non-critical visuals
- keep motion smooth but efficient
Measurement
Use Lighthouse and Vercel Analytics regularly after each major update.
Bottom line
Performance is a growth feature, not a technical extra.
