• 750: Bug fixes:
  • Match layout values to panel IDs so reordered keys map to the correct constraints
  • Preserve keyboard mappings for disabled separators; fixes edge case “Matching panels not found” error
  • Respect default layout when an initially hidden group becomes visible
  • Calculate available group size once per hit-testing pass instead of once per hit region
  • Ensure onLayoutChanged still fires when pressing elsewhere on the page or resizing another group
