hey! weird one with vp dev + TanStack Start.
route: ssr: false, works in prod build. but in dev, browser module graph pulls in react-dom/server.browser.js from
somewhere deep and throws does not provide an export named 'default'. tried a custom Vite plugin to shim react-dom/server
→ no luck.
vibecoder disclaimer: i don't actually code lol, i've got an AI agent (acting as a engineer) doing the actual
work while i just vibe and point. so forgive me if i'm missing something basic — the agent's been digging for hours and
we're both stuck.
is there something about how Vite+ handles the dev SSR module graph that could cause this? any config flag i should
try? or should i just file this on the TanStack side?

Can you provide a code repository that can reproduce the issue?
