My application loads slowly. Here are the Lighthouse metrics and network waterfall: [PASTE_METRICS]. Identify the [3-5] optimizations with the highest impact on LCP, FID, and CLS. For each optimization, explain: the expected impact in milliseconds, the implementation difficulty, and provide the necessary code or configuration.

Pour cibler les bonnes optimisations, commence par isoler le type de ressource qui bloque le LCP (image, police, JS). Utilise l'onglet "Timings" de la cascade réseau pour identifier les goulots d'étranglement. Une astuce : priorise les optimisations "quick wins" comme le préchargement des polices critiques et le lazy loading des images non visibles, qui impactent directement FID et CLS avec un faible effort.
