Adding support for custom css per domain?

[iamkoby]

Root layout is in the app folder and there's no access to head in the domain level even though for all matters it should be the root layer.

@steven-tey this is such a basic functionality that couldn't find any solution for... wasted tens of hours on this... normally you would just edit the root layout but you can't include domain specific data in the root layout because domain is subfolder...

also can't revalidate cache on single domain...
