//! `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.
