Produce a single-page printable invoice.

## Workflow

   - Two columns: From (sender) / Bill to (recipient) with addresses.
   - Project ref + payment-terms strip.
   - Line items table: description / qty / unit / amount.
   - Right-aligned totals block: subtotal, retainer, tax, total due.
   - Payment instructions (bank, wire, ACH).
   - Thank-you note + signature line.
3. Print stylesheet @media print to remove backgrounds.
