The /style.css route 500'd in production because style.css is gitignored and the Dockerfile never produced it: only main.py and templates/ were copied into the image. Mirror the myice Dockerfile by building the CSS in the builder stage: copy the tailwind input files, download the standalone Tailwind CLI (arch-aware for x64/arm64), and compile style.css. The artifact is then copied into the runtime stage. build-css.sh is kept for local dev but not used in Docker because its #!/bin/bash shebang and pipefail are incompatible with alpine's sh.
