Production build FOUC

I seem to be having an issue with production builds having FUOC on the initial render. My Production builds are launched via Vercel

I am using the following:

"@tanstack/react-query": "^5.66.0",
"@tanstack/react-query-devtools": "^5.66.0",
"@tanstack/react-router": "^1.125.6",
"@tanstack/react-router-devtools": "^1.125.6",
"@tanstack/react-router-with-query": "^1.125.6",
"@tanstack/react-start": "^1.125.6",

"@tailwindcss/postcss": "^4.1.11",
"tailwindcss": "^4.1.11",

Layout.tsx----

import appCss from '@/styles/app.css?url';
header...
{ rel: 'stylesheet', href: appCss },
