/* ── The account pages: sign in, create an account, codes, passwords ──────
 *
 * One narrow card in the middle of a light page. The same shape for every
 * step, so moving from "sign in" to "check your email" to "choose a new
 * password" reads as one task rather than five different screens.
 *
 * The primary button is full width inside the card: on a phone that is where
 * the thumb already is, and on a desktop a card this narrow has no "right
 * side" for a small button to sit on.
