Setting Performance Budgets Your Team Will Actually Keep

A performance budget only works if it's enforced automatically — bundle-size checks in CI catch regressions long before a manual Lighthouse run would.

Dynamic imports for below-the-fold, interaction-heavy sections (carousels, modals, charts) consistently gave the biggest wins with the least risk.

The hardest part isn't the tooling, it's the review culture: treating a bundle-size increase the same way you'd treat a failing test.
