Current qualitative deepening pass for the FROG Tab widget family
FROG — Free Open Graphical Language
The Tab family now has a fuller public surface for page navigation and page hosting:
- structured
frog.tab_selectionvalue model, - stable page identity,
- selected page posture,
- tab header layout posture,
- page region and page container surfaces,
- overflow and tab scrolling surfaces,
- optional close and reorder posture,
- tab item icon / label / close-button parts,
- selected-page container and content parts.
Tab remains a page navigation and container widget family. It does not own child-widget values, hidden page lifecycle internals, host-native tab handles, or IDE-private page editors.
