/**
 * Plans / upgrade widget — shown by `show_plans`, and by any generation the
 * server refused for credits.
 *
 * Rendered NATIVELY from structuredContent. It used to iframe
 * app.kolbo.ai/pricing/embed, which needs `frameDomains` in the widget CSP —
 * OpenAI rejected the ChatGPT app for exactly that on 2026-09-06 ("frameDomains
 * is reserved for limited cases where embedding a third-party experience is
 * essential"). Prices here are the live, promo-adjusted numbers the server
 * fetched from /v1/account/plans at call time; Buy/Subscribe open
 * https://app.kolbo.ai/pricing in a new tab — Stripe and the user's session
 * never run inside a host iframe.
 *
 * structuredContent contract:
 * {
 *   widget: 'plans',
 *   reason: 'insufficient_credits' | 'requested',
 *   balance, required, shortfall,     // when reason === 'insufficient_credits'
 *   current_plan: { key, name },
 *   plans:        [{ key, name, interval, credits, price, original_price,
 *                    discount_percent, promo_text, currency, top_up_discount }],
