+# Multi-stage build: Node 22 build -> Nginx serve static SPA

+FROM node:22-alpine AS builder

+WORKDIR /app
+
+# Copy workspace manifests first for better layer caching
+COPY package.json package-lock.json ./
+COPY apps/web/package.json ./apps/web/package.json
+
+# Install all workspace dependencies (root + apps/web).
+#
+# Workaround for npm's optional-dependencies bug (npm/cli#4828): the committed
+# lockfile does not contain the musl-native rollup binary, so `npm ci` inside
+# this Alpine (musl) image skips it and `vite build` fails with
+# "Cannot find module @rollup/rollup-linux-x64-musl". After installing, verify
+# that rollup (and its platform-native binary) actually loads; if it does not,
+# fall back to a reconciling `npm install`, which resolves and installs the
+# correct platform binaries from the registry.

+# ---------- Stage 2: Serve with Nginx ----------
+FROM nginx:1.27-alpine AS runner
