# syntax=docker/dockerfile:1
#
# Single multi-stage Dockerfile for ECHODO. Build via Docker Compose with
# `target:` to select web | collab | mcp.
#
# Why one file instead of three?
#   - The `deps` stage runs `pnpm install` ONCE for all 723 workspace packages.
#     BuildKit shares it across every downstream target by content hash, so
#     web + collab + mcp build in parallel without three concurrent installs
#     blowing through the build host's RAM.
#   - Per-app build stages (`web-build`, `collab-build`, `mcp-build`) only
#     copy the source they actually need.
#   - Final runtime stages (`web`, `collab`, `mcp`) pull just the built
#     artifacts and the per-app node_modules they need at runtime.
