ludus::ui::Context¶

Class

One main-thread context per surface.

Initialization allocates bounded storage; document resolution/input never allocate. Documents are copied, with no borrows retained. Failure preserves the last committed layout and input state. Spans expire on the next successful TrySetDocument or context destruction.
