# =============================================================================
# FlowWink frontend — self-hosted deployment (Easypanel, Docker, any VPS)
# =============================================================================
# Multi-stage: Node builds the Vite SPA, nginx serves the static output using
# the nginx.conf checked into the repo root (SPA routing, caching, /health).
#
# Supabase target resolution (see docs/operators/self-hosted-frontend.md):
#   1. RUNTIME: container env VITE_SUPABASE_URL / _PUBLISHABLE_KEY /
#      _PROJECT_ID — the entrypoint regenerates /runtime-config.js on every
#      start, so one image serves any instance (switch = restart).
#   2. FALLBACK: the same vars as build args, baked into the bundle:
#
#   docker build \
#     --build-arg VITE_SUPABASE_URL=https://<ref>.supabase.co \
#     --build-arg VITE_SUPABASE_PUBLISHABLE_KEY=<anon-key> \
#     --build-arg VITE_SUPABASE_PROJECT_ID=<ref> \
#     -t flowwink .
