// esbuild build for @hive/dashboard. Outputs:
//
//   dist/app.js          bundled ES module (entrypoint = src/app.js,
//                        pulls in @hive/shared + marked)
//   dist/dashboard.css   bundled stylesheet (entrypoint = src/dashboard.css,
//                        @import "@hive/shared/base.css" + terminal.css
//                        get inlined here)
//   dist/index.html      copy of src/index.html (esbuild doesn't process
//                        HTML; the script/link tags reference the bundled
//                        siblings by name)
//
// Both Rust binaries serve `dist/` via tower_http::ServeDir. The output
// must keep the same filenames the existing index.html references, so
// downstream changes are mechanical.
