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.

Sora Prompt for Brainstorming Ideas
Sora, OpenAI's video generation model, is not limited to creating finished clips. It's a powerful tool for brainstorming visual ideas, exploring creative concepts, and bringing still-abstract visions to life. By crafting exploratory prompts, you can use Sora as a visual thinking partner: test atmospheres, narrative styles, artistic directions, or scene setups before committing to a full production. Whether you're a filmmaker, art director, content creator, or entrepreneur, this approach lets you quickly generate video mockups that serve as starting points for your projects. The key advantage is iteration speed: where a traditional storyboard takes hours, Sora delivers a first visualization in seconds. You can explore ten creative directions in the time it would normally take to develop just one. The prompts presented here are designed to maximize result diversity and stimulate your creativity, rather than produce a perfect final render.
