+/**
+ * Populate `src/web/public/vendor/` with the browser bundles the mobile tests need.
+ *
+ * The mobile suite (test/mobile/**) drives a real browser against a WebServer
+ * started from TypeScript source, so fastify-static serves
+ * `join(__dirname, 'public')` = `src/web/public` — NOT `dist/web/public`, where
+ * `npm run build` puts the vendor bundles. Every `/vendor/xterm*` request 404s,
+ * so `Terminal` is never defined, `initTerminal()` never runs, and every test
+ * touching `app.terminal` dies with `Cannot read properties of null`.
+ *
+ * That stayed invisible because config/vitest.ci.config.ts excludes
+ * `test/mobile/**`, so CI never ran the suite.
+ *
+ * Mirrors the vendor steps in scripts/build.mjs, targeting the source tree.
+ * Same inputs and output names, so the page markup needs no test-only branch.
+ * `src/web/public/vendor/` is gitignored, so these stay build artifacts.
+ *
+ * Idempotent: skips outputs already newer than their source.
