     * track here, shared with intel's `auto` track below it. Since CSS Grid
     * track sizing is independent of a flex CHILD's own inline height, the
     * original js/layout-resizer.js (which only ever set #main-panel's own
     * flex/height) had NO way to actually reallocate space between the main
     * and intel rows at this breakpoint -- dragging the handle was a no-op
     * here even after the handle itself became visible, because #main-panel
     * simply doesn't control its own grid row's size once main+intel stack.
     * --taskboard-row-size (set by layout-resizer.js only in stacked/tablet
     * mode) lets the resizer directly control this row's track size instead,
     * which correctly grows/shrinks main at intel's expense. Defaults to 1fr
     * (identical to prior behavior) when the JS hasn't set anything yet. */
