/// GitHub's auto-generated tag archive won't have them — and rust-embed
/// silently embeds nothing, shipping a binary whose web UI renders unstyled
/// (issue #233). Fail the build with instructions instead. Both the crates.io
/// package and the `cook-<version>-source.tar.gz` release asset include the
/// compiled assets, so neither `cargo install cookcli` nor a build from that
/// tarball needs Node.js.

        These files are generated and not checked into git, so they are absent\n\

        Without them the web UI (`cook server`, `cook build web`) renders\n\
        unstyled pages. To build without Node.js, use a source drop that ships\n\
        them prebuilt: the `cook-<version>-source.tar.gz` asset on the GitHub\n\
        release, or the crates.io package (`cargo install cookcli`)."
