A 2D scene is just a Scene: persistent 2D content lives in the ECS like everything else. Canvas stays separate as immediate-mode drawing (see the Canvas immediate-mode issue).

What already exists

CameraComponent with Projection::Orthographic
TransformComponent: position.xy for placement, position.z (or a separate sort key) for draw order, rotate only around Z
Scene views, hierarchy/inspector panels, scene registry

Needed

SpriteComponent: texture handle, color/tint, size, and maybe UV rect / pivot
Maybe a ShapeComponent for untextured quads/circles
A 2D render system in SceneRenderer that batches sprites, sorted by draw order
Texture resource + pool, if there isn't one yet
Inspector support for the new components

Done when

A scene with an orthographic camera and sprite entities renders in a scene view
Sprites can be added/edited through the editor inspector
An example (e.g. port boids_2d) uses a 2D scene instead of Canvas
