# build.ps1 — Clean, fast Docker build script for PragatiVeer v2
# ─────────────────────────────────────────────────────────────────────────
# What this script does:
#   1. Enables Docker BuildKit (required for --mount=type=cache to work)
#   2. Runs `docker compose build --parallel` which:
#      - Builds backend image ONCE and tags it as pragativeer-backend:local
#      - worker + beat containers reuse that image (no rebuild)
#      - BuildKit caches pip wheels and npm packages between builds
# ─────────────────────────────────────────────────────────────────────────
