⚠️ CRITICAL FORMATTING RULES (READ BEFORE USING)

1. Escape Newlines: If using --text via CLI, you MUST escape newlines as \\n.
   • ❌ Wrong: --text "Line 1\nLine 2" (Shell eats the backslash)
   • ✅ Right: --text "Line 1\\nLine 2"
2. Prefer File Input: For any content longer than one line, ALWAYS use --text-file.
   • ✅ Best: echo "Line 1\nLine 2" > msg.md && node send.js ... --text-file msg.md
   • This avoids ALL shell escaping issues.
3. Markdown Support: Supports Bold, Italic, Links.
   • ⚠️ Code Blocks: Support is limited. Use single backticks `code` for safety.
