Keep foreign buyers on normal e-commerce invoice flow (TIN EI00000000020) instead of consolidated mode.
Use country-aware buyer state mapping to avoid sending Malaysian state codes for non-Malaysian countries (prevents CV316).
2.1.1

2.1.0
Improved nonce validation in user profile TIN save handler based on WordPress.org review feedback.
Documented external LHDN API/portal services and domains in readme files.
