/**
 * Radius sign-in menus (`S` → Radius when no credential is stored): the two
 * choices pi's `/login radius` offers, then pi's OAuth method menu.
 *
 *   ┌─ Radius sign-in ─────────────────────────────── alpha ─┐
 *   │ › Sign in with an account                              │
 *   │   Sign in with an API key                              │
 *   └────────────────────────────────────────────────────────┘
 *   ┌─ Choose how to sign in to Radius ────────────── alpha ─┐
 *   │ › Sign in with browser                                 │
 *   │   Sign in with device code                             │
 *   └────────────────────────────────────────────────────────┘
 *    SHARE │ j/k move   Enter select   Esc cancel
 *
 * Both are ./select-dialog.ts presets. The account path then asks pi's own
 * OAuth question (browser / device code) in the second menu; the API key
 * arrives through ./input-dialog.ts. pi's labels carry parenthetical asides
 * ("(recommended)", "(when signing in from another device)") — the panel
 * shows the plain choice through the i18n keys below. Only text and
 * callbacks — no I/O.
 *
 * Radius 登录方式菜单：账号（OAuth）/ API Key，和 pi 的 `/login radius` 一致。
 * 账号之后 pi 会问浏览器 / 设备码，也用同一个菜单，文案换成面板自己的
 * （pi 原文里括号中的说明不显示）。API Key 用输入框。
