6) Tips for previews and metadata
- Set OG meta (title/description/image) for correct previews in VK/Telegram.
- Keep title ≤ 60–70, description ≤ 140–160 for universal visibility.
- Place key benefits in the first 1–2 lines of the description.
- Check previews before publishing (via drafts/preview bots/sharing).
