Page Data
The JSON the page owns, and the store it becomes at runtime.
The Keys and JSON views of Logic → Data.
Logic → Data is the page's seed state: a JSON object whose paths bindings, units and reactions all read and write. It has two faces of the same data — Keys, a clickable tree that binding picks from, and JSON, the raw document that authors keys.
{
"title": "My Scene",
"score": 0,
"items": []
}- The root must be a JSON object; an array or a scalar is rejected.
- Invalid JSON is reported inline and nothing is written.
- Format tidies the document; applying shows a brief Saved indicator.
- Arming a field for binding forces the Keys view forward.
