 Return a single JSON object with exactly these top-level keys: `characters`, `interactions`, `objects`, `environment`, `camera`, `lighting`, `metadata`. All keys MUST be present; empty sections are empty arrays (and `metadata` is an object).
 
-Each character has an integer `id` (its 0-based index) and the concept arrays `identity`, `appearance`, `clothing`, `accessories`, `pose`, `expression`, `actions`. Each interaction has `participants` (an array of character ids) and a `concept` string. Concepts are plain strings (semantic concepts, never tags).

Each interaction has `participants` (an array of character ids) and a `concept` string.
