new_editor is an isolated playground for the XCUI experiment. It is intentionally separated from the main editor so you can redesign the UI stack without destabilizing the current ImGui-based editor.

Current scope

Provides a minimal Win32 + ImGui host (scaffolded elsewhere) that links the engine and XCUI code.
Hosts a single demo panel that loads XCUI documents and reroutes draw commands through ImGuiTransitionBackend.
Bundles themed XCUI documents under resources/ so the demo can run without touching the primary editor's assets.

Resources

resources/xcui_demo_view.xcui describes the card layout, placeholder texts, and debug markers the demo renders. resources/xcui_demo_theme.xctheme defines colors, spacing, and tokenized styles that the runtime resolves.

Next steps

Expand the demo UI to exercise more layout primitives (stack, grid, overlays) and token-based styling.
Hook the runtime into actual document hot-reload so the panel responds to source edits.
Use new_editor to prototype a native XCUI shell before deciding whether to migrate the real editor.
