/* Widget gallery on the home page (#28).
 *
 * The gallery is authored as a plain HTML table in README.md so it renders on
 * GitHub too. Bootstrap styles that table with rules and cell padding that read
 * as a data table rather than a set of chart cards, so undo that here. Scoped to
 * the table immediately following the Gallery heading, leaving the widget /
 * workflow table further down the page with its default styling.
