The standalone build runs on macOS and bundles darwin-arm64 native sharp binaries. These crash immediately on the Alpine Linux container, causing the Node process to exit and Dokploy's reverse proxy to return a 502 Bad Gateway. This adds a RUN step to remove the macOS binaries and install the correct @img/sharp-linuxmusl-x64 package at build time.
