//
// Usage:
//   node tg-update.js "<HTML-formatted text>"
//   node tg-update.js --file <path-to-text-file>      (preferred for multi-line)
//
// Architecture:
//   This script does NOT talk to Telegram directly. It POSTs the announcement to
//   the bobai-tg-bot Cloudflare Worker's /broadcast endpoint, authenticated with a
//   shared BROADCAST_SECRET. The worker then sends two messages via its own
//   BOT_TOKEN (a CF secret that never leaves Cloudflare):
//     1) A lone 🧠 — Telegram renders 1-3 emoji-only messages as JUMBO, which
//        acts as the visual "this is an update" header for every announcement.
//     2) The actual text with parse_mode=HTML.
//
// .env requires:
//   BROADCAST_SECRET  — shared secret between this script and the worker
//                        (set on CF with: npx wrangler secret put BROADCAST_SECRET
//                        --config worker-tg-bot/wrangler.toml)
