/**
* Smoke test — renders an invoice PDF for a synthetic order matching the
* style of `data/rechnung.png` (1× Bluetooth Tracker @ 5,99 EUR × 6, B2B
* customer "Schmidhofer Dienstleistungen" with UID ATU57680511) and writes
* it to `data/sample-rechnung.pdf` for visual review.
*
* Also runs assertions on:
* - VAT calculations
* - GiroCode payload shape
* - IBAN validation
* - Numbering allocation in both modes
* - Notice derivation for B2B EU reverse-charge / export / Kleinunternehmer
*
* Run with: npx tsx scripts/render-sample.ts
