• LCP — Hero image and headline must appear quickly
• INP — Buttons and forms must feel instant
• CLS — No layout jumps that make people mis-tap Call

Fixes that move the needle

3. Defer non-critical scripts (chat widgets after first interaction)
4. Use modern image formats (AVIF/WebP)
5. Keep third-party tags under control via GTM discipline
