Style Extractor

Extract a unified style anchor from the script or reference materials,match the most suitable style from the predefined style library, and generate a style asset package to ensure visual consistency across the entire production.

Core Principles

Style library first: Must be selected from the predefined style library; custom styles are prohibited
Overall style first: The "style segment" of all shot prompts may only reference STYLE_BASE or STYLE_VAR, and must not be arbitrarily rewritten per shot
Variants only write increments: STYLE_VAR may only write "change items (delta) that differ from BASE"; rewriting BASE is prohibited
Consistency first: Once the style anchor is determined, it is frozen for the entire production and may not be modified arbitrarily
