[Video](https://zenit.z.express/media/stories/tooltip.mp4?v=64c28daff2)

**BEHAVIOR CONTRACT**

**RECORDED INTERACTION**

Der virtuelle Cursor fährt über den Top-Trigger und die Blase erscheint.

`examples/storybook/stories.zig:2475`

```zig
// ── Tooltip ──
pub fn buildTooltip(scope: *ui.Scope, cx: *ui.Cx) anyerror!*ui.Node {
    const a = cx.allocator;
    const c = try col(cx, 12);
    try c.appendChild(a, try label(cx, "Hover a button to see the tooltip (4 positions)"));

    // 四个主方向各一个 trigger，间距大些避免弹层重叠。
    const grid = try ui.box(cx, .{ .direction = .row, .gap = 24, .align_items = .center }, .{});
    const positions = [_]struct { p: W.tooltip.TooltipPosition, t: []const u8 }{
        .{ .p = .top, .t = "Top" },
        .{ .p = .bottom, .t = "Bottom" },
        .{ .p = .left, .t = "Left" },
        .{ .p = .right, .t = "Right" },
    };
    inline for (positions) |spec| {
        const tt = try W.Tooltip(.{ .text = spec.t ++ " tooltip", .position = spec.p }).mount(scope, cx);
        try tt.trigger.appendChild(a, try W.Button(.{ .label = spec.t, .variant = .secondary }).mount(scope, cx));
        try grid.appendChild(a, tt.wrapper);
    }
    try c.appendChild(a, grid);
    return c;
}
