escriba-render 0.1.33

escriba-render — rendering trait + implementations.

Two backends, same trait surface:

• [TextRenderer] — ANSI-in-stdout for CI / headless runs.
• [gpu::GpuRenderer] — madori + garasu + glyphon real GPU window. Implements [madori::RenderCallback]; the escriba binary pairs it with an on_event handler that shares an Arc<Mutex<EditorState>>.
