 * The predictor lives inside page.php, which wraps content in

 * to ~160px — far smaller than the 360px home grid columns.
 * Override the page wrapper's constraint so the predictor grid
 * gets the same available width as the home grid (1440px).
 * padding-inline: 0 removes the page wrapper's side padding;
