/*
 * Account UI: the header slot, the avatar menu, the sign-in dialog, and the
 * toast the account flow needs on pages that don't load styles.css.
 *
 * A third stylesheet rather than blocks in both styles.css and pages.css:
 * these components appear on all four pages, and the tokens below are already
 * declared twice in this repo — a third copy of ~250 lines would have drifted
 * within a release.
 *
 * Values come from the account-flow design canvas. They resolve to the same
 * palette both existing stylesheets define, with fallbacks so this file is
 * self-contained if it ever loads alone.

/*
 * The UA stylesheet's `[hidden] { display: none }` is the WEAKEST rule there
 * is: any author rule that sets `display` beats it. Several components here
 * are flex containers toggled via the hidden property, so without this they
 * set the attribute and stay visible — which shipped once, rendering the
 * provider list and the OTP pane at the same time.
 *
 * styles.css solves this per selector (`.share-overlay[hidden]`, …). One rule
 * is safer: a new toggled element cannot forget to opt in.
