• 1.3 Add a pasted shipping-info input and parse recipient name, recipient phone, and address content into editable form fields
• 1.4 Compose the selected region text and detailed address into recipient_address when submitting /api/c/v1/exchange/{id}/shipping-info
• 1.5 Preserve edit compatibility for previously saved combined addresses

2. Homepage ICCID Summary

• 3.4 Verify the homepage top summary shows ICCID from /api/c/v1/asset/info above the package name
