Let me read the current files to make the changes.

Now I'll save the images to local files and make all the changes. Let me update the pricing section to only have the Premium plan, update all links to the new checkout URL, and add photos to the testimonials.

Now let me update all the components:

Now let me also remove the upsell modal since there's no basic plan anymore, and clean up the page if it imports it:

Good, the page.tsx doesn't import the upsell modal directly (it was imported inside pricing-section.tsx which I already rewrote without it). Let me also update the social proof notifications to use the new link:

Pronto! Fiz todas as alteracoes solicitadas: removi o plano basico e deixei apenas o Premium (R$69,90) centralizado na pagina, atualizei todos os botoes de checkout para o novo link da Lowify, adicionei as 3 fotos enviadas aos primeiros depoimentos como se fossem imagens enviadas pelos alunos, e removi o modal de upsell que nao faz mais sentido sem o plano basico.

The screenshot shows a Vercel deployment error: "Vulnerable version of Next.js detected, please update immediately" (CVE-2025-66478). I need to update the Next.js version in package.json.
