# peo4c: neo4j-browser on top of PostgreSQL + Apache AGE.
#
# Stage 1 builds the neo4j-browser static frontend from source.
# Stage 2 is the Apache AGE image (PostgreSQL with the AGE extension) plus the
# peo4c bridge, which speaks the Bolt protocol to the browser and translates
# Cypher into AGE `cypher()` calls.
