Framework import screenshots moved to Vercel Blob

Patch Changes

• c95a7ca: Move framework import screenshots from Cloudinary (assets.vercel.com) to Vercel Blob. The four affected entries (Next.js, Nuxt, SvelteKit, SvelteKit legacy) now point at https://py8fhxnkzwtsqdo9.public.blob.vercel-storage.com/front/import/*.png. Same images, different host — consumers see no behavior change.
