# The hybrid deploy:
# one command - `docker compose -f deploy/docker-compose.yml up --build`.
#
#   static  -> the immutable half: the Go single binary serves prerendered
#              documents, build-precompressed brotli, ETag 304s and the SPA
#              fallback, logs one access line per request to stdout and
#              answers /metrics (Prometheus text format).
#   dynamic -> the live half: server actions, /api handlers, middleware,
#              $data - the Node server, same code, same compiler output.
#
# Every request the static half cannot answer itself (any POST, any /api
# route without a baked body) is reverse-proxied to `dynamic` via UPSTREAM.
# Drop the UPSTREAM line and the static service becomes the pure-static
# deploy: POSTs answer 405, unbaked APIs answer the JSON 404.
