Blue's terminal renderer and the repository's only pi-tui adapter. It owns terminal startup/shutdown, raw mode, alternate screen, focus, keyboard dispatch, layout, themes, node validation/compilation, and visible width.

Core subscribes directly to ctx.bluePanes and ctx.blueOverlays. Pane/overlay render functions return renderer-neutral BlueUiNode values; core validates and compiles them into concrete components. There is no plugin host or bridge between the registry and renderer. Visible passive bottom panes stack by priority above the editor, while focusable panes retain tab selection.

Core also owns rich terminal rendering: the shared Markdown adapter enhances closed Mermaid fences, while structured chart nodes are adapted through the active semantic theme. Invalid, unsafe, over-quota, or over-wide input remains visible through width-contained source or text fallbacks.

The package also exposes low-level blueScreen, blueKeymap, blueTerminalInfo, blueComponents, and theme services for Blue's own TUI packages.
