/* ── The offer, and what is left of it ──────────────────────────────────────
   Two faces of one fact. Signed out it is `.pane-offer`: the reason to make an
   account. Signed in it is `.pane-credit`: what that grant has left. They are
   styled as a pair on purpose — the promise and the receipt should look like
   the same object, because a visitor who acted on the first is owed the
   second in the same visual language. */
