Inspector
The property editor for the current selection, section by section.
Raw CSS for anything the sections do not cover.
Advanced is collapsed by default and holds the escape hatch: any style key not surfaced elsewhere, a raw JSON editor for the whole style object, and a key/value pair to add a new property.
- The JSON textarea replaces the node's style wholesale; invalid JSON is rejected with “Invalid JSON” and nothing is written.
- With several nodes selected, only keys shared by every selected type are applied — the rest are ignored.
- Adding a key that is not shared across the selected types is refused with a message naming the key.
