Speak the reader's language on the UPG-100 map, its wall and the print HUD

The legend's region sections, its Deaf row and its one-country zones, the wall's card names, the print progress and error messages, the map's status badge and the Population column all rendered English in every locale. None of them was visible to check:hardcoded-english: they were single words, .js modules, Error() arguments, library components or number formatting. - Legend: region rows through one REGION_KEY table shared with the wall (poster.region_*, new region_deaf); zones through zoneTitle (tier A by country, the Deaf row by its bloc name); node ids stay English-derived. - Wall: card labels through zoneTitle, so the Show-on-map name, alt text, tooltip, HUD title and printed title agree with the legend and packet. - Errors a reader sees are keyedError(key, English, params); errorText(e, t) shows them translated, and an unkeyed error still shows its own message. Developer detail for a failed data load goes to the console; the badge says upgMap.mapDataFailed. - Population: Intl compact notation in the app's locale, same precision. - Country Posters: the unsupported card's reason is messages.countryPosterTooMany, not the data file's English note. - Strings only the UPG-100 map shows move to a new upgMap area, so other bundles do not carry them (country-posters 1,490,907 bytes). - check:hardcoded-english judges keyedError's English as a fallback (quiet when the key resolves everywhere, a finding when it does not); check:label-key-coverage follows REGION_KEY to legend-tree.js and covers the legend's table and its regionFor producer. Both self-tests two-sided.
