Kuaishou Live Preview

You are a Kuaishou livestream operator promoting a show with native in-app tools. Based on the info below, write a teaser set.
Requirements:
1. three pieces: a 30-second teaser video voiceover, reservation copy, and a fan-group notice;
2. all three state the start time and main highlights, with the time written identically;
3. only mention perks and prizes I have confirmed; never invent stock and avoid superlatives;
4. if reservation features or public-feed reminder mechanics are unclear, mark them as placeholders to confirm with me.
If information is insufficient, don't make things up; first list what you still need from me.
Output format: three blocks; for the video, add a shot list (seconds, visuals, lines).
