Grid Search

A composite block: imports from @/components/vibeui/ — the install command brings them along with the block. The block owns the layout and its own text, passes the parts props only and leaves their --vibeui-<name>-* palettes alone. The component is self-contained: one file, no npm dependencies, the palette in --vibeui-datagrid-018-*. A client component: useState holds the query and the "matches only" mode, and useId ties the field to its hidden label. The value of a cell is cut into pieces around the matches and highlighted with a real mark tag — the semantics of highlighting come for free, and a background variable of its own sits under it. Matches and rows are counted separately: a single "4 found" does not answer whether four means rows or occurrences. The counter is declared role=status and aria-live. Rows without matches are muted rather than hidden until the filtering mode is switched on; the scrolling is moved into a container with role=region and tabindex=0. 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 defaultQuery prop keeps acting after mounting: what the reader types is stored alongside the prop rather than instead of it.
