# Multi-stage production Dockerfile for the Vite frontend
#
# Builder stage: node:24-alpine with corepack pnpm, runs
# frozen-lockfile install and pnpm build to produce the
# dist output. Runtime stage: nginx:alpine, removes the
# default config, copies vigil.conf and the built assets
# to the nginx html root. Includes a HEALTHCHECK on /health.
# Connects to compose.yml, infra/nginx/vigil.conf
