Avalonia-first terminal UI

`RoyalApps.RoyalTerminal.Avalonia` provides a backend-neutral `TerminalControl` with theming, virtualization, regex text highlighting, framebuffer shaders, capture/replay, snapshot export, and rich input handling.

Multi-transport runtime

PTY, pipe, SSH, raw TCP, Telnet, and serial transports share a single session model and option surface.

Managed and native VT engines

Choose the managed `BasicVtProcessor`, the native Ghostty-backed processor, or the default factory with deterministic fallback behavior.

Modular rendering stack

Use the Skia cell renderer and shader post-process pipeline alone or add Ghostty renderer interop packages and native assets where they fit your host architecture.

Production validation surface

The repository includes an Avalonia demo, a control catalog, headless/UI tests, integration tests, native packaging checks, and benchmarks.

Repository-scale documentation

This guide covers the source tree outside the `external/ghostty` submodule with feature-led articles plus generated API reference pages for the public managed packages.
