// Package adminconsole renders the server-side operator console mounted by the
// backend under the `/_gm` route group.
//
// The console is a multi-page, server-rendered surface built on the standard
// library's html/template package: navigation is driven by request path and
// query, state changes are submitted with HTML forms and answered with a
// Post/Redirect/Get redirect. The package owns three concerns and nothing
// transport-specific:
//
//   - Renderer composes the shared layout with one content page per route.
//   - CSRF issues and verifies the stateless anti-CSRF token embedded in every
//     state-changing form.
//   - Assets exposes the embedded stylesheet served under `/_gm/assets/`.
//
// The gin glue (route registration, Basic Auth, the CSRF guard middleware, and
// the per-page handlers) lives in package server; this package stays free of
// the web framework so it can be unit-tested in isolation.
