Doxa Maps bc422bb678 Each packet's % evangelical page states its own list's share
The page says each box is a share of the people in this list. It
printed one DOXA-wide figure - 0.6133% of 209,079,159 people - in
every packet, true of no single list.

That figure had no builder in the repo. build-evangelical-share.mjs
makes its method reproducible, per group: the IMB CSV joined to the
DOXA snapshot by ROP3 + country, each group's EvangelicalLevel band at
its midpoint (0 for No Known Evangelicals, the midpoint read from the
band's own wording), weighted by IMB population. It writes
evangelical-by-slug.json and refuses to write unless the table, summed
over every DOXA group, reproduces christian-share.json exactly: 2,091
matched, 209,079,159 people, 1,282,178 evangelical, 0.6133%. Change a
single band's midpoint rule and it refuses.

Not the API's imb_gsec: GSEC puts 225 groups at "no evangelicals" where
EvangelicalLevel puts 1,444, because its "less than 2%" band also
carries church-planting status. A share from it sits on a different
scale from the method the page's own footnote states.

evangelicalShare.js sums a packet's own groups - pure, zero imports, so
the browser print and the offline generator run the same sum. Across
the 28 zones the page now carries 28 different figures, from 0.182%
(Deaf) to 0.922%. A host that supplies its own figure still wins.

A list with no published levels prints a dash and no number. The old
guard, Number.isFinite(Number(x)), passes null as 0 and would have
printed "0% evangelical" for no data. Where some of a list's groups
lack a level, the footnote says what the figure is computed over; it
says nothing when coverage is whole. That clause is in all eleven
languages.

check-evangelical-share (gates:pre): the table reproduces the committed
figure; different lists differ; no data is a dash; coverage appears
only when partial. Mutation-tested four ways, each caught - the fourth
only once it corrupted an existing group rather than adding one no sum
reads.
