The United States catalogue now includes additional verified normal stamp listings while preserving existing collector data.
Changes
- Added duplicate-safe StampWorld BASE comparison and guarded catalogue import for future countries.

- Corrected structured cent and dollar values so imported denominations display in their original units.
- Preserved existing Stamp and Issue identities, Collections, Wishlists, images, and manual data.
