/**
 * ResttyTerminalView — TerminalView over the primary Restty API
 * (libghostty-vt WASM + WebGPU/WebGL2).
 *
 * Configured for Ghostty parity via {@link buildGhosttyParity}:
 * full Nerd Font weight set, Symbols Nerd Font, Ghostty default theme,
 * WebGPU-first renderer, ligatures, linear-corrected blending, window padding.
 *
 * I/O model:
 * - Keys: AvocadoPtyTransport (connected) → avocado PTY (no local echo)
 * - Display: avocado PTY output → Restty.sendInput(text, "pty")
 * - Resize: engine-driven only (transport.resize / fit); host-driven resizes
 *   use transport.withHostResizeSuppressed to avoid feedback loops
