Constants

• **IMAGE_MODEL = `gemini-3-pro-image-preview`** — Paperbanana (Nano Banana Pro) for image rendering
• **REASONING_MODEL = `gemini-3-pro-preview`** — Gemini for layout optimization and style checking
• **MAX_ITERATIONS = 5** — Maximum refinement rounds
• **TARGET_SCORE = 9** — Minimum acceptable score (1-10) — RAISED FOR QUALITY
• **OUTPUT_DIR = `figures/ai_generated/`** — Output directory
• **API_KEY_ENV = `GEMINI_API_KEY`** — Environment variable

Optional: Style reference (`— style-ref: <source>`, opt-in)

Lets the user steer **structural** figure conventions (caption length, panel-count distribution, figure-to-table ratio in the parent paper) toward a reference paper. **Default OFF — when the user does not pass `— style-ref`, do nothing differently from before.**

Only when `— style-ref: <source>` appears in `$ARGUMENTS`, run the helper FIRST, before generating prompts:

# Resolve $STYLE_HELPER via the canonical strict-safe chain (see
# shared-references/integration-contract.md §2). Policy A — gate:
# unresolved helper means --style-ref cannot be satisfied, so abort.
