The Teamer app groups hotels by cost unit and renders a flag per
destination, and cannot derive either from what /api/hotels returns
today.
costUnit is the raw kostenstelle and stays a string: only 281 of 1931
hotels carry one and some hold a space-separated list such as "84 85".
countryCode goes through CountryCodeMapper, whose table is part of the
API contract: BusPro's land column mixes ISO-2, ISO-3 and European
vehicle registration codes for the same country, and a wrong entry
mislabels a destination's flag silently. An unmappable token is null and
warns on the bpn channel, never a guess. country itself is untouched --
it remains the join key into /api/countries[].token.
