Function draw_scene_tile 

fn draw_scene_tile(
    ui: &mut Ui,
    path: &Path,
    current_scene: &Path,
    start_scene: &Path,
    renaming_scene: &mut Option<PathBuf>,
    scene_rename_buffer: &mut String,
    requests: &mut UiRequests,
)

One tile: a placeholder icon (see draw_model_tile’s doc comment — no cheap thumbnail for a scene either), highlighted if it’s the scene currently open for editing and starred if it’s the project’s start scene. Double-click switches to it (opening a new tab if it isn’t already open — see EditorScene::switch_or_open_scene — or just activating its existing tab, no reload, if it is); the context menu offers Rename (inline, like the Scripts section’s) and “Set as Start Scene”. Renaming only touches the file on disk, ProjectManifest.start_scene, and any open tab’s identity — unlike a ScriptAttachment path (structured ECS data rename_script can fix up everywhere it’s referenced), a scene.change("path") call is a free-text string literal inside .rhai source that can’t be auto-fixed, so a renamed scene’s incoming scene.change(...) calls (if any) are left dangling and need updating by hand.
