join(', ') is English list grammar. The two user-facing sites now go through the library's formatList (Intl.ListFormat, R29), as conjunctions because each is the FULL list:
- PPLR's Rosetta popup, "Not yet cross-mapped in PPLR: {ids}";
- UPG Neighbor's bridge-language cards, "Believers in: {list}".
Key Cities' shortened language list follows once its "{n} more" key (keyCities.list.moreLanguages) is on development. The joins that stay are not reader lists: a thrown error's details, the bridge-languages CSV columns, and a gate's console line.
