"""Theme packages — TCSS stylesheets, vocabulary, command aliases, narrative tone.

A theme is a configuration package with:
- TCSS stylesheet (colors, borders, text styles)
- Command aliases (themed names for canonical commands)
- Vocabulary (what to call missions, chains, etc.)
- Narrative tone (instructions for LLM prompt injection)

v1 ships with Film Noir as the default and only theme.
