+// Compute the platform-specific `extraResources` entry for bundling the
+// EternalTerminal `et` client. Lives under scripts/ (eslint-ignored) so it
+// can use Node CommonJS globals freely; consumed from
+// electron-builder.config.cjs.
+//
+// Binaries are produced by .github/workflows/build-et-binaries.yml and
+// downloaded into resources/et/<platform-arch>/ by
+// scripts/fetch-et-binaries.cjs (gated on ET_BIN_RELEASE).
+//
+// We only emit the directive when the binary is actually on disk so that
+// `npm run pack` keeps working without a bundled et — for example, when the
+// developer skipped the fetch step or the relevant arch hasn't been built
+// yet.
+//
+// Unlike mosh-client, `et` is a pure network-transport client and does not
+// render a terminal locally, so there is no terminfo bundle to package.
