/**
 * Inline fetch-failure state with retry. Errors render inline, never as
 * toasts (toasts are for success feedback).
 *
 * Auth failures mostly SELF-HEAL: rest.js refreshes the REST nonce via core's
 * admin-ajax `rest-nonce` action and retries once. What can still land here:
 *   saddle_analytics_signed_out  — the refresh itself failed: session is dead
 *   rest_cookie_invalid_nonce    — a fresh nonce was rejected too (rare)
 *   rest_forbidden + 401         — credentials stripped before WordPress
 *   rest_forbidden + 403         — signed in without manage_options
