# Build context: ./web (see docker-compose.debug.yml). Source is bind-
# mounted over /app at container start, so this image only installs deps —
# no COPY of source, no build step here.

# Real Node for the dev server. The bun image has no node, so vite's
# `#!/usr/bin/env node` shebang resolves to Bun's node-fallback shim — and
# under Bun, node-http-proxy (vite's server.proxy) never gets the client
# 'upgrade' event, so every proxied WebSocket (browser → vite → Go server)
# hangs in CONNECTING forever while the server logs a successful accept
# (oven-sh/bun#10441). Bun stays for dependency install only.

# Source is bind-mounted over /app in the debug compose stack, so Vite HMR
# picks up changes live — no image rebuild needed. --host so the container's
# port mapping can reach it.
