```zig
pub fn buildWordNav(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, "Word navigation — Alt+←/→ jumps whole Greek/Cyrillic words; double-click selects the word; family emoji is one cluster"));

    const ta = try W.Textarea(.{
        .label_text = "Mixed-script sample",
        .value = WORDNAV_TEXT,
        .rows = 3,
        .width = 560,
    }).mount(scope, cx);
    ta.meta.ownership.meta.test_id = "story.wordnav.ta";
    try c.appendChild(a, ta);

    try c.appendChild(a, try label(cx, "Expected Alt+Right stops (byte offsets): 7 14 27 34 40 46 72 75"));
    return c;
}
```
