Found and fixed in a Windows pass of everyday workflows: unsaved documents are now copied in the background (at most every 10 s) and offered back after a crash or forced quit (file.recover); Ctrl+arrow / Ctrl+Backspace / Ctrl+Delete text motion follows Windows and Linux conventions (keymap::text_motion); number-field scrubbing keeps its value; typing in a Tab-focused field works; default linear gradients and their handles behave; Escape closes dialogs without deselecting; clipped panel hints wrap; the unsaved-changes dialog is translated.

//! FigCraft's MCP server.
|
|
//!
|
|
//! [Model Context Protocol](https://modelcontextprotocol.io) over stdio: newline-delimited JSON-RPC
|
|
//! 2.0, hand-written (no async runtime). The server exposes FigCraft as MCP tools, resources and
|
|
//! prompts, and forwards everything to a [`Backend`]:
|
|
//!
|
|
//! - [`Headless`] hosts an in-process [`figcraft_engine::Session`] and answers the control-channel
|
|
//! methods itself (rendering with `figcraft-render`), so agents can design without a window.
|
|
//! - [`Attached`] talks to a running desktop app through its loopback JSON-lines control channel
|
|
//! (`figcraft --control PORT`): one `{"id","method","params"}` line in, one
|
|
//! `{"id","ok","result"|"error"}` line out.
|
|
//!
|
|
//! Entry points: [`Server::serve`] (stdio loop) and [`Server::handle_line`] (one message).
