Avoid browser globals in Vite SSR entries

Run this rule

pnpm vite-doctor . --framework vite --rules vite/ssr/no-browser-global-in-ssr-entry

Why it matters

Server-rendered markup must match the first client render. Browser-only state, time, randomness, or hash-sensitive URLs can create hydration mismatches.

Recommended fix

Remove browser global in SSR entry, or move it to the Vite runtime/API that owns that behavior.
