Ensure address hierarchy

When dealing with international or even national shipping, it makes sense to put the country/state name first for checkout. Many fields, such as address or phone number, are region-specific, so knowing the country/state ensures you only ask for relevant information.

Since address formats could be different in different regions, provide users with tools to speed up the process. Indicate the meaning of each required input with a label and example placeholder text, such as street name or apartment number.
