# Give the two pds.js dev PDSes an account each.
#
# pds.js hosts one account per instance and has no signup endpoint that works
# over plain http — its server-side onboarding bakes an https:// endpoint into
# the genesis PLC operation, which nothing local can reach. So identities are
# minted the way the runclub example mints them: pds.js's own setup script,
# which registers a did:plc naming the PDS URL verbatim and then hands the key
# to the server through /init.
#
# Needs a pds.js checkout. Point PDSJS_DIR at it if it isn't ~/code/pds.js.
#
#   docker compose up -d
#   ./seeds/pdsjs-accounts.sh
#
# Private keys land in data/, which is gitignored. Re-running against a PDS
# that already has an account fails at /init; `docker compose down -v` first.
