7 habits for frontend performance

Performance isn’t a one-time cleanup before launch; it’s a daily habit. Here are the ones I repeat most:

1. Ask if the image can be smaller — modern formats, right-sized dimensions
2. Don’t load every font — font-display: swap saves your life
3. Static when you can — build-time beats runtime, always
4. Animate only transform and opacity — avoid layout thrash
5. Lazy-load below-the-fold content
6. Delete unused dependencies — every byte of bundle counts
7. Measure on a real network, not just localhost

No silver bullet, but these add up into a noticeably better experience.
