+//! `RenderPlan` — comandos materializados para backends que no
+//! reciben llamadas en vivo (SVG export, snapshot testing).
+//!
+//! Un painter que escribe contra [`crate::Canvas`] puede ser
+//! capturado en un `RenderPlan` usando un `Canvas` adapter que
+//! empuja `RenderCmd`s en lugar de dibujar. El exporter consume
+//! el plan y emite `<polyline>` / `<rect>` / etc.
