# ──────────────────────────────────────────────────────────────────────────────
# FitMart — Full-Stack Docker Compose
#
# Services:  mongodb | server | client
#
# Usage:
#   1. Copy server/.env.example → server/.env and fill in your values.
#      NEVER commit .env files or serviceAccountKey.json to git.
#   2. Run: docker compose up --build
#   3. Open http://localhost (client) and http://localhost:5000 (API)
#
# Secrets:
#   Firebase credentials and Razorpay keys are read from server/.env at
#   runtime — they are never baked into the image.
