/**
 * Drift guard for the curated drug-reference data (upstream #1040 follow-up).
 *
 *   node --experimental-strip-types tests/standalone/curated_data_sync.standalone.ts
 *
 * The `collections/*.json` files are the single source of truth; the matching
 * `app/data/*.ts` modules are generated from them (`npm run gen:curated-data`).
 * This test fails if a generated module ever drifts from its JSON — i.e. if
 * someone hand-edited the `.ts` instead of the JSON, or forgot to regenerate.
 * A failure means: edit the JSON, then run `npm run gen:curated-data`.
