# NEXT_PUBLIC_* values are inlined into the browser bundle by `next build`, so the API URL and site origin
# are BUILD-time inputs, not runtime env vars — setting them in compose would do nothing. They come from the
# committed .env.production, which `next build` reads because it runs with NODE_ENV=production; change a value
# there and rebuild the image.
