"""Regenerate the aspirin example dashboard from its committed source data.

    uv run python skills/retrosynthesis_planning/examples/build_example.py

`aspirin_routes.json` holds AiZynthFinder-shaped route trees and
`aspirin_annotations.json` holds deterministic demonstration annotations — they
are illustrative text, not experimental evidence for aspirin manufacturing.

Molecule depictions come from RDKit when it is importable, and from the
transparent placeholder SVG otherwise. Install RDKit before regenerating if you
want the example to show real structures.
