/**
 * render-live-route.ts — the live 3D route ENTRY (the generic player).
 *
 * This file contains NO scene-specific content. It loads whatever EpisodeDocument is
 * injected (a Director-GENERATED scene, the working document, or an explicitly chosen
 * example) and hands it to the GENERIC `scene-player`, which can render ANY document.
 *
 * IMPORTANT: there is NO content fixture as the default. When nothing is injected the
 * route plays a neutral EMPTY placeholder and prints a clear "no scene loaded" message.
 * The Moon Garden scene is now an EXAMPLE (`src/examples/moon-garden.example.ts`) and is
 * used ONLY when explicitly requested — never as the default render path.
 *
 * This is the bridge for both project goals:
 * generalization = a Director GENERATES documents; studio = an agent EDITS documents.
