How the SunYou → Poste Italiane handoff works

Follow the parcel across both networks without waiting on asynchronous webhooks or losing visibility at the handoff boundary.

1. SunYou Origin Sortation (China)
SunYou collects the parcel (`SY...` / `SYIT...`) and assigns an Italian Poste Italiane Crono (`UW...IT` or `3C...`) barcode.
2. European Air Transit & Customs Release
Shipments fly into Liège or Milan Malpensa, clear EU IOSS customs, and truck into Poste Italiane's Milan/Piacenza/Bologna hubs.
3. Poste Italiane / SDA Delivery
Poste Italiane scans `In consegna` and delivers the parcel to your Italian address.
Secondary Barcode Resolution
SunYou links the `SY...` / `SYIT...` origin number to the Italian `UW...IT` or `3C...` Poste Italiane barcode.
Single-Call Tracking
`GET /v1/track/{number}` merges SunYou export milestones with Poste Italiane last-mile scans.

const headers = { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` };
const originRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}`, { headers });
const originPkg = await originRes.json();

// Extract secondary barcode from top-level message ("Final mile tracking: UW482910554IT (Poste Italiane)")
const handoff = originPkg.message?.match(/^Handed to (.+?) as ([A-Z0-9-]+)$/i);
if (handoff) {
  const [, , lastMileNumber] = handoff;
  const destRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(lastMileNumber)}`, { headers });
  const destPkg = await destRes.json();
