/**
 * Receipt-parser smoke test (tick 14).
 *
 * Sanity-checks that scripts/parse-receipts.js routes each fixture to the
 * right adapter and extracts brand + title + price. No real Gmail calls,
 * no DB writes — pure function-call asserts against inline fixtures.
 *
 * Run:
 *   node scripts/test-receipts.js
 *
 * Exit code is 0 on all-pass, 1 on any failure.
