/**
 * Magic link helper for payment-return pages.
 *
 * The customer store now owns all token decoding (see stores/customer.js:
 * `hydrateFromToken`). This composable is a thin read-through so the
 * payment pages can render `v-if="auth.authenticated"` without caring
 * about where the session came from (magic-link URL vs. existing nav).
 *
 * The router guard already calls `store.hydrateFromToken()` before these
 * pages mount, so by the time this runs the store is either hydrated or
 * still empty — no extra decoding needed here.
