TV Episode Cold Open Design

Design a cold open for a {{genre}} TV series with the following parameters:

Series Premise: {{series_premise}}
Episode Theme: {{episode_theme}}
Season Position: {{season_episode}}

The cold open should:
- Hook viewers within the first 30 seconds
- Establish or subvert the episode's central question
- Reference ongoing series mythology if applicable
- End on a moment that demands the title card

Write the full cold open (2-3 pages) in TV screenplay format, then explain how it sets up the episode's A-story.
