+ * This app proxies nothing.
+ *
+ * /api, /auth, /install, /update and /public are the Go server's, and routing
+ * them there is the reverse proxy's job — the same proxy that already
+ * terminates TLS in front of this process. Next used to rewrite them itself
+ * from an API_URL naming the control plane, which meant every deployment had
+ * two possible request paths for the same URL and one environment variable
+ * that silently broke a whole prefix when it named the wrong host: pointed at
+ * the marketing site, /public/status/... 404'd as a page that does not exist,
+ * indistinguishable from a status page that does not exist.
+ *
+ * Browser calls are same-origin and relative (see lib/api.ts), and the public
+ * status page's server-side fetch is made against the visitor's own host, so
+ * nothing in this app needs to know the control plane's address any more.
