/*
  Sign in and create an account.

  Everything here is prefixed `auth-`. `.brand` and `.btn` are borrowed on purpose — the wordmark
  and the hero's button, so these screens read as the same product rather than as a login bolted
  onto it.

  NO COLOUR ON THE ERROR STATE, and that is a decision rather than an omission. This host has one
  accent, teal, and it means "grew". The negative value in docs/design/README.md's table
  (#E8674F) was validated on the admin host's grounds, not these, and that file says to re-run the
  check rather than move a value across. So an error is carried by weight, position and
  role="alert". Give it a colour once the ramp has been measured here.
