Detailed Description

RenderSession - the headless render-session core used by REPL and tooling. Owns the current document state (URI, raw bytes, rendered bitmap) and exposes a narrow state-transition API that higher layers can call into.

This is deliberately UI-free: no ImGui, no GLFW, no GL, no stdin/stdout. The UI layer takes an EditorApp& and drives it - tests can do the same. right now the only mutation the MVP supports is "navigate to a new URI and re-render."

Rendering is performed in-process through svg::Renderer.

RenderSessionStatus

enum class donner::editor::app::RenderSessionStatus

strong

High-level state the editor can be in. The REPL uses this to decide what status chip / prompt decoration to show the user.

Enumerator
kEmpty	No document loaded yet.
kLoading	Navigation in flight (rare - rendering is synchronous today).
kRendered	A bitmap is available and was rendered cleanly.
kFetchError	Source loading failed. Previous bitmap is retained.
kParseError	Parser returned an error. Previous bitmap is retained.
kRenderError	Rasterization failed post-parse. Previous bitmap is retained.
