Seed words read down each column; the Google central is a parameter with a door to the previous one.

Word grids flow down a column then the next, with the row count from the
word count — on a phone the first column is 1–6, the way a hand copies a
list. pomegranate.js takes the central as an option (CENTRALS.coinos is
auth.coinos.io, now deployed; the default stays auth.njump.me until its
Google client is live), and the sign-in card grows a "previous server"
line once the default moves, so accounts made under njump keep working.
