⚙️ Admin Setup — 2 steps:
1. Open this file, find the CONFIG block in the <script> and replace YOUR_BLOGGER_BLOG_ID with your Blog ID (Blogger → Settings → Basic → Blog ID).
2. Replace YOUR_GOOGLE_API_KEY with a Google API key that has the Blogger API v3 enabled (Enable here → Credentials → Create API Key).
Both values must be set before the live feed works. Until then, demo posts are shown.
