## 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:

```bash
# Resolve $STYLE_HELPER via the canonical strict-safe chain (see
# shared-references/integration-contract.md §2). Policy A — gate:
# unresolved helper means --style-ref cannot be satisfied, so abort.
cd "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" || exit 1
if [ -z "${ARIS_REPO:-}" ] && [ -f .aris/installed-skills.txt ]; then
    ARIS_REPO=$(awk -F'\t' '$1=="repo_root"{print $2; exit}' .aris/installed-skills.txt 2>/dev/null) || true
fi
if [ -z "${ARIS_REPO:-}" ] && [ -f "$HOME/.aris/repo" ]; then
    ARIS_REPO=$(cat "$HOME/.aris/repo" 2>/dev/null) || true
fi
STYLE_HELPER=".aris/tools/extract_paper_style.py"
[ -f "$STYLE_HELPER" ] || STYLE_HELPER="tools/extract_paper_style.py"
[ -f "$STYLE_HELPER" ] || { [ -n "${ARIS_REPO:-}" ] && STYLE_HELPER="$ARIS_REPO/tools/extract_paper_style.py"; }
[ -f "$STYLE_HELPER" ] || {
  echo "ERROR: extract_paper_style.py not resolved at .aris/tools/, tools/, \$ARIS_REPO/tools/, or via ~/.aris/repo." >&2
  echo "       Fix: rerun bash tools/install_aris.sh or smart_update.sh (refreshes ~/.aris/repo), export ARIS_REPO, or copy the helper to tools/." >&2
  echo "       --style-ref cannot be satisfied; aborting." >&2
  exit 1
}
STYLE_STATUS=0
CACHE=$(python3 "$STYLE_HELPER" --source "<source>") || STYLE_STATUS=$?
case "$STYLE_STATUS" in
  0) ;;                                       # use $CACHE/style_profile.md as structural guidance
  2) echo "warning: style-ref skipped (missing optional dep)" >&2 ;;
  3) echo "error: --style-ref source failed; aborting illustration" >&2 ; exit 1 ;;
  *) echo "error: helper failed unexpectedly; aborting illustration" >&2 ; exit 1 ;;
esac

Sources accepted: local TeX dir / file, local PDF, arXiv id, http(s) URL. Overleaf URLs/IDs are rejected — clone via `/overleaf-sync setup <id>` first and pass the local clone path.

**Strict rules** (full contract in `tools/extract_paper_style.py` docstring):

- Use `style_profile.md` to align caption length and figure density with the reference paper. The CVPR/ICLR/NeurIPS visual standards above still take precedence — `--style-ref` only refines length-and-density tendencies, never image content.
- **Never copy figure content, color palettes, or specific design elements** from anything reachable through the cache. The visual design comes from the user's prompt, not the reference.
- **Never pass `— style-ref` (or the cache contents) to the Claude vision-checker / Gemini reasoning-checker sub-agents** when they score the generated image — the image must be judged on its own merits.

## CVPR/ICLR/NeurIPS Top-Tier Conference Style Guide

**What "CVPR Style" Actually Means:**

### Visual Standards
- **Clean white background** — No decorative patterns or gradients (unless subtle)
- **Sans-serif fonts** — Arial, Helvetica, or Computer Modern; minimum 14pt
- **Subtle color palette** — Not rainbow colors; use 3-5 coordinated colors
