/**
 * WeChat scan-to-sign-in / scan-to-bind card and the shared auth card.
 *
 * The same stylesheet serves both layouts: on the frontend the sukanTheme
 * `--sukan-*` custom properties are present, while the OJS backend falls back
 * to literal values matching the native backend UI (#006798, #ddd borders,
 * 0.25rem radius).
 *
 * The literal fallbacks intentionally target the backend only: on the
 * frontend the theme tokens always resolve, so these values never take
 * effect there. Do not "correct" them to the frontend token values.
 *
 * Frontend page shell: every frontend page of the `sukanAuth` router (scan
 * sign-in, OAuth pending, anonymous sign-in error) renders as the same
 * full-width white card as the theme auth pages (login/register), with the
 * sidebar suppressed; the content inside becomes a centered, width-capped
 * column without its own card chrome. The backend bind pages keep the card
 * chrome from the base rules below.
