/* Auth pages — onboarding, login, OAuth callback. Tokens come from shared.css.
   Spacing variable names there are --s1..--s8 (not --space-N). Card uses
   8px radius vs the dashboard's 4px because auth is a single-moment surface
   that benefits from a slightly more deliberate, "stop and read" presence. */
