# EPPP Docker Compose baseline — [E00-S02-T01]
#
# `docker compose up -d` starts both the database (PostgreSQL) and the
# application (@personal-blog/server). Rollback: `docker compose down`.
#
# Explicitly out of scope for T01 (land in later E00-S02 tasks):
#   - PostgreSQL health gate (T02)
#   - application health endpoint (T03)
#   - DB volume persistence (T04)
#
# All values have defaults so `docker compose up -d` works from a clean clone
# without a .env file (a committed .env.example template lands in E00-S04).
