// The UI abstraction surface. `main.zig` and `image.zig` program against THIS
// module (importing `"ui"`) instead of libvaxis directly, so the rendering +
// input backend can be swapped at build time (`-Dui=vaxis|sdl`).
//
// This is the *vaxis* (real terminal) backend: a transparent passthrough. It
// re-exports the libvaxis declarations the app uses, so every type (`Key`,
// `Mouse`, `Window`, `Cell`, …), the `Vaxis` renderer/loop, `Tty`, and `init`
// are exactly libvaxis's. All the UI logic therefore behaves identically to the
// pre-refactor app — this file exists purely as the seam a different backend
// (`ui_sdl.zig`) can replace.
//
// (Zig 0.16 dropped `pub usingnamespace`, so the re-export is explicit.)
