# aiw-voice-app: React SPA built with Vite, served by nginx as static files.
# Multi-stage so the runtime image carries no node_modules.

# Build args:
#   VITE_MODE   "production" (default, prod build) or "staging" (dev-domain build)
#               Vite picks .env.<mode> automatically - see aiw-voice-app/.env.* files.
