/**

|
|
* i18n PR4 — subdivisions.
|
||
|
|
*
|
||
|
|
* Validates:
|
||
|
|
* 1. Major countries (PL, US, CA, GB, AU) return non-empty lists
|
||
|
|
* 2. Sample known codes resolve to expected names
|
||
|
|
* 3. hasSubdivisions correctly classifies micro-states with no subs
|
||
|
|
* 4. Validation rejects garbage codes
|
||
|
|
* 5. getSubdivisionName returns the human name
