- * ÐΛɌ₭ᑎΞ𐒡𐒡 https://github.com/DarknessShade
- * Bot API 10.1
+ * Telegram Rich Markdown & Channel Formatter Bot — Cloudflare Worker
+ *
+ * Features:
+ * - Direct Messages: Renders any Markdown/HTML sent to the bot.
+ * - Channels: Automatically formats posts containing Markdown/HTML tags on publish.
+ * - Smart Edit Detection: Ignores posts without formatting to avoid unnecessary (edited) marks.
+ * - Per-channel disconnect & channel-only tag guide.
+ * - Admin Panel: /stats and /broadcast (Restricted to ADMIN_ID).
+ * - Persistent KV Cache for users, channels, and stats tracking.

 /**
  * Telegram Rich Markdown & Channel Formatter Bot — Cloudflare Worker
  *
- * Features:
- * - Direct Messages: Renders any Markdown/HTML sent to the bot.
- * - Channels: Automatically formats posts containing Markdown/HTML tags on publish.
- * - Smart Edit Detection: Ignores posts without formatting to avoid unnecessary (edited) marks.
- * - Per-channel disconnect & channel-only tag guide.
- * - Admin Panel: /stats and /broadcast (Restricted to ADMIN_ID).
- * - Persistent KV Cache for users, channels, and stats tracking.
+ * Core:
+ * - DMs: render Markdown (with inline HTML) as Rich Messages.
+ * - Channels: auto-format posts on publish (smart edit detection).
+ * - Per-channel disconnect, channel-only tag guide.
+ * - Admin Panel, KV cache.
+ * - Manual spacing preserved (NBSP), auto-slideshow, pull-quote, map shortcut.
+ *
+ * NEW:
+ * 1) Live preview: every DM render shows "📤 Publish to channel" buttons.
+ * 2) Time shortcut: [زمان: ...] / [time: ...] -> <tg-time>.
+ * 3) Auto channel footer (multi-link), set & remove anytime. (FIXED)
+ * 4) Better /stats dashboard (channels, footers, today, 7-day chart).
+ * 5) Undo: /undo in PM -> bot asks to revert the channel's last render to raw.
+ * 6) Tag Render Settings: Per-channel toggle for specific tags via glass buttons.
