13th Tehran Maktab Festival reaches final stage

I'm ready to translate the Persian news summary to professional English while maintaining the exact structure and markers you've specified.

However, I notice you've only provided the headline/title:

**سیزدهمین فستیوال مکتب تهران در ایستگاه پایانی**

**Translation:**

The Thirteenth Tehran School Festival at the Final Station

Please provide the full content with the lead paragraph (▸), bullet points (•), and coverage-difference paragraph (◆) so I can translate the complete summary.
