Tanstack start without tailwind (css modules, zero runtime css-in-js, anything but tailwind)
Reason being is I have legacy design systems implemented with styled-components and it is significantly easier to migrate to zero-runtime css-in-js or css modules and our team is quite good at writing clean styles without a million utility classes.
The core error revolves around FOUC (Flash of unstyled content) when the app renders.
I have a starter monorepo here https://github.com/j-mcfarlane/tanstack-start-monorepo that has a FOUC error. It is using pigment css (pigment only works with 18.3 if you upgrade to 19 it wont work).
Additionally there is an open issue on tanstack/router with a css modules example https://github.com/TanStack/router/issues/3023 with the same FOUC issues.
Has anyone gotten tanstack start working with (anything but tailwind) css modules or zero-runtime css in js? Would be grateful for any examples
