+# 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
+# ─────────────────────────────────────────────────────────────────────────
