What does it unlock?
App initialization flag variable. Signals when MetaBox has completed loading.
Practical Application
Use the viewportReady event (more reliable) to gate your UI rendering — don't show controls until MetaBox confirms it's ready.
AI Coding Best Practices
Prefer the viewportReady event over this variable: api.addEventListener('viewportReady', (ready) => { if(ready) enableUI(); }).
viewportReady is the reliable signal that MetaBox is ready to accept commands.
