    // Thing is, @prisma/client has generated code. So users end up with a stale @prisma/client
    // when they change their prisma schema and regenerate the client, until clearing out node_modules/.vite
    // We can't exclude @prisma/client from optimizeDeps since we need it there for @cloudflare/vite-plugin to work.
    // But we can manually invalidate the cache if the prisma schema changes.
