Newly generated projects pin the Tailwind CLI to 4.3.0. That release's macOS arm64 binary fails code signature validation and is killed on macOS 27, so `mix phx.server` never builds priv/static/assets/css/app.css and the generated app renders unstyled. The upstream fix shipped in 4.3.1, and 4.3.3 is the current release.
