The Driver reported the list page being slow and guessed the posters. The
posters are behind a v-if and never load until a region is opened. The cost
was the mount fetch: it requested the full PEOPLE_GROUP_LIST_FIELDS for every
people group, and this page renders none of it -- a region's label, group
count, country count and country names all come from country_code and
wagf_region alone. Verified by running summarizeRegions on two-field rows:
the four values this page binds all come out.
SIZE OF THE SAVING: NOT MEASURED, and I will not put a number on it. Six of
eight fields are dropped per row across the whole dataset, including two
coordinates, a population integer and three status/count fields, so the
reduction is real -- but sizing it needs the live endpoint, which I cannot
call from here. My first attempt quoted a proxy off
public/assets/people-groups/people-groups-slim.json; that file is the IMB
dataset in PascalCase and carries NONE of the eight field names, so both
halves of that comparison were measuring empty objects. The figure was
meaningless and is removed rather than rounded.
PEOPLE_GROUP_LIST_FIELDS is untouched: the dashboard tab needs all eight for
its map pins and stat cards.
