#!/usr/bin/env bash
#
# build-stage.sh — Build the Stage marketing image (neuron-web + soul-demo).
#
# Pipeline:
#   1. Stage the foundation El runtime into ./runtime/.
#   2. Compile client-side El sources (src/js/*.el) to dist/js/*.js using
#      the JS-capable elc binary at bin/elc-linux-amd64 (CI) or the local
#      elc (dev). Output is gitignored and rebuilt every run.
#   3. Concatenate src/*.el into dist/main-combined.el (component-first,
#      main.el last; matches the historical order from build-local.sh).
#   4. Compile dist/main-combined.el → dist/main.c using the canonical
#      native elc at foundation/el/dist/platform/elc.
#   5. Inject the host-side stub forward declarations into dist/main.c
#      (sed header rewrite, same set as the prior in-Dockerfile sed).
#   6. docker buildx build --platform linux/amd64 -f Dockerfile.stage.
#
# bootstrap.py is no longer in the build path. The container image now
# expects dist/main.c to be a finished C source — it just runs cc on it.
#
# Usage:
#   ./build-stage.sh <tag>           — build marketing:<tag>
