录像展示 neutral / accent / status 颜色和 outline。

`examples/storybook/stories.zig:552`

```zig
// ── Tag ──
pub fn buildTag(scope: *ui.Scope, cx: *ui.Cx) anyerror!*ui.Node {
    const a = cx.allocator;
    const c = try col(cx, 12);

    // ── 全部颜色（含 info）──
    const r1 = try row(cx, 8);
    inline for (.{ W.TagColor.neutral, .accent, .success, .warning, .danger, .info }, .{ "neutral", "accent", "success", "warning", "danger", "info" }) |col_, t| {
        try r1.appendChild(a, try W.Tag(.{ .text = t, .color = col_ }).mount(scope, cx));
    }
    try c.appendChild(a, try label(cx, "Colors"));
    try c.appendChild(a, r1);

    // ── 尺寸 ──
    try c.appendChild(a, try label(cx, "Sizes (sm / md)"));
    const r_sz = try row(cx, 8);
    inline for (.{ W.TagSize.sm, .md }, .{ "Small", "Medium" }) |sz, t| {
        try r_sz.appendChild(a, try W.Tag(.{ .text = t, .color = .accent, .size = sz }).mount(scope, cx));
    }
    try c.appendChild(a, r_sz);

    // ── 变体 ──
    try c.appendChild(a, try label(cx, "Variants"));
    const r2 = try row(cx, 8);
    try r2.appendChild(a, try W.Tag(.{ .text = "Default", .variant = .default }).mount(scope, cx));
    try r2.appendChild(a, try W.Tag(.{ .text = "Outline", .variant = .outline }).mount(scope, cx));
    try r2.appendChild(a, try W.Tag(.{ .text = "Closable", .closable = true }).mount(scope, cx));
    try r2.appendChild(a, try W.Tag(.{ .text = "Outline + close", .variant = .outline, .color = .danger, .closable = true }).mount(scope, cx));
    try c.appendChild(a, r2);
    return c;
}
```

[在 GitHub 查看源码examples/storybook/stories.zig:552](https://github.com/version-next/zenit/blob/HEAD/examples/storybook/stories.zig#L552)

这是 Storybook 中该 story 的原样代码（zenit 5f9add5+wip 2026-09-30）。其中 `W` 即 `ui.widgets`，`col` / `row` / `label` 是 Storybook 内的布局小工具。

### TagProps

`ui.widgets.Tag`

[src/ui/components/tag/mod.zig:77](https://github.com/version-next/zenit/blob/HEAD/src/ui/components/tag/mod.zig#L77)

fn Tag(props: TagProps) TagBuilder
```

| 字段 | 类型 | 默认值 | 说明 |
| --- | --- | --- | --- |
| `text` | `[]const u8` | `""` | — |
| `variant` | `TagVariant` `.default` `.outline` | `.default` | — |
| `color` | `TagColor` `.neutral` `.accent` `.success` `.warning` `.danger` `.info` | `.neutral` | — |
| `size` | `TagSize` `.sm` `.md` | `.md` | — |
| `closable` | `bool` | `false` | — |
| `on_close` | `?core.HandlerRef` | `null` | — |
| `close_icon_asset` | `?svg_assets.Asset` | `null` | — |

### \*Node

`ui.widgets.Tag`

mount 直接返回 `*Node`，把它 append 到父节点即可。
