   NACMU platform - shared design language

   The admin design system's tokens, shared by every module: the module
   bar that sits on top of each module, the account pages (sign-in,
   password, onboarding) and the platform-level status pages.
   Everything is namespaced (.pdock, .pf-*) so it can be loaded into any
   module without touching that module's own styles.
