Saved Views

The component is self-contained: one file, no dependencies, the palette in --vibeui-datagrid-020-*. A client component: useState holds the list of views, the active name and the current state separately from it. Comparing the current state with the saved one gives the "changed" marker — without it there is no telling whether you are looking at a view or already at something of your own; the save button is blocked while there are no changes. The tabs lie in a nav with aria-label, and the active one is marked aria-current rather than by colour alone. A view stores both the filter and the sort: half a restored state is worse than none. The theme comes from the surrounding color-scheme through light-dark(): by default the grid lays no panel under itself, it sits directly on the page background and darkens along with it. The views and startView props keep acting after mounting: the reader's edits are stored alongside them rather than instead of them.
