Crate ftui_backend 

Backend traits for FrankenTUI: platform abstraction for input, presentation, and time.

This crate defines the boundary between the ftui runtime and platform-specific implementations (native terminal via ftui-tty, WASM via ftui-web).

See ADR-008 for the design rationale.

Structs

BackendFeatures

Terminal feature toggles that backends must support.

Traits

Backend

Unified backend combining clock, event source, and presenter.

BackendClock

Monotonic clock abstraction.

BackendEventSource

Event source abstraction: terminal size queries, feature toggles, and event I/O.

BackendPresenter

Presentation abstraction: UI rendering and log output.
