Why speed matters
Fast websites increase conversions and rank better. Aim for sub‑2s LCP and 90+ Lighthouse.
Core actions
- Compress images (`webp`), responsive sizes, and lazy-loading.
- Defer non-critical scripts; keep JS small and modular.
- Use Tailwind typography scale and consistent spacing.
- HTTP caching and CDN (Netlify/Vercel/Cloudflare).
International UX
- Readable fonts, accessible color contrast, RTL support if needed.
- Currency, date formats, and copy localized for target regions.
