"""Anytime Mailbox Setup — virtual mailbox provisioning for out-of-state formations.

When a carrier forms in Wyoming but operates elsewhere, they need a Wyoming
mailing address for official correspondence. We use Anytime Mailbox for this.

Setup requires USPS Form 1583 — notarized authorization for mail receipt.
The customer's photo ID (already collected during intake) is used for the 1583.

Flow:
  1. Customer orders Wyoming formation package
  2. LLC is formed in Wyoming
  3. We open an Anytime Mailbox in Wyoming under the LLC name
  4. Generate USPS Form 1583 pre-filled with customer + LLC info
  5. Customer e-signs the 1583 via our portal
  6. Schedule online notarization session (same service as CRTC BITS)
  7. Submit notarized 1583 to Anytime Mailbox
  8. Mailbox active — address provided to customer
