The canvas now fills the window and the chat floats on its right. draw.io is served from our own origin (public/drawio, downloaded at build time and checked against the release's SHA-256), so the app can drive the editor directly: - every AI change becomes a version card with a thumbnail; compare, restore or undo it, and Ctrl+Z on the canvas takes an AI change back in one step - shapes the AI just changed are highlighted on the canvas - selected shapes appear as a chip and are sent to the model - draw.io's own simple UI: its toolbar, menus (auto layout, Mermaid, CSV import) and page tabs; the shape library starts closed - new start screen, session rename and switcher, open .drawio files - settings split into Models & keys, Appearance, Advanced and About - Bedrock in the model settings also takes an API key instead of access keys - phones switch between canvas and chat - dark mode uses draw.io's own dark mode, with neutral greys around it With an external draw.io (NEXT_PUBLIC_DRAWIO_BASE_URL) the features above that need same origin are off. The chat logic moved from the 1500-line chat panel into a chat engine plus small UI components; zustand holds canvas, versions, settings and UI state.
