+ * A plugin install runs `npm install --omit=dev`, so a package listed only in
+ * devDependencies — or one that arrived only as some other package's
+ * dependency — is missing there. v2.8.9 crashed at start on every plugin
+ * install: `js-yaml` (server/lib/lane-detect.js) was a devDependency that
+ * `redoc` used to pull in, and dropping `redoc` took it away. Machines with
+ * Debian's global /usr/share/nodejs never saw it, so this checks the manifest
+ * instead of trusting a local `require` to fail.
