# NODE_ENV=production must NOT be set in this stage: with it set, `npm ci`
# skips devDependencies (vite, @tailwindcss/vite, etc.) that `npm run build`
# itself needs (SolidStart's build runs through vite) - the build then fails
# with ERR_MODULE_NOT_FOUND for 'vite'. It belongs in the runtime stage only,
# where it actually affects the running server, not here.

# GATEWAY_URL is resolved at runtime from the process environment (see
# src/lib/server/gateway.ts), not baked in at build time.
