      ```tsx lines expandable theme={null}
      import { UserMessage } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <UserMessage
            content="Hey — can you take a look at this?"
            timestamp={new Date(2026, 3, 1, 16, 40)}
          />
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

    To use the `UserMessage`, pass `content` and a required `timestamp`. The bubble right-aligns with a 24px left gutter. The kit forbids `children`.

    ```tsx theme={null}
    import { UserMessage } from "@servicetitan/anvil2-ai-kit";

    function ExampleComponent() {
      return (
        <UserMessage
          content="Can you look at this invoice?"
          timestamp={sentAt}
        />
      );
    }
    ```

    `content` accepts a string, inline markup, or a Markdown tree. Copy is text-only: pass `copyText` when `content` is rich so the copy action stays available. When neither yields text, the copy button is omitted.

    ### Content length

    Long messages wrap inside the bubble.

    <LiveCode showCode example="ai-kit-user-message-content-length" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { UserMessage } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <div
            style={{
              display: "flex",
              flexDirection: "column",
              gap: 16,
              maxWidth: "48rem",
            }}
          >
            {/* Short */}
            <UserMessage
              content="Hey — can you take a look at this?"
              timestamp={new Date(2026, 3, 1, 16, 40)}
            />

            {/* Long — wraps at the 640px cap */}
            <UserMessage
              content="Here's a longer message that exceeds the comfortable single-line width of the bubble, so it wraps onto multiple lines and never exceeds the 640px cap."
              timestamp={new Date(2026, 3, 1, 16, 41)}
            />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Error and retry

    Pass `error` to render a line below the bubble. `onRetry` shows a refresh action only when `error` is also set.

    <LiveCode showCode example="ai-kit-user-message-error" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { UserMessage } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <UserMessage
            content="Can you look at this?"
            error="Message not delivered."
            onRetry={() => {}}
            timestamp={new Date(2026, 3, 1, 16, 40)}
          />
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Toolbar

    The toolbar always includes copy (when copyable) and the formatted timestamp. Set `revealToolbarOnHover` so a chat list can hide the toolbar until hover or focus, typically on every message except the latest. Coarse pointers always show the toolbar. Keyboard focus reveals it.

      ```tsx lines expandable theme={null}
      import { UserMessage } from "@servicetitan/anvil2-ai-kit";

            style={{
              display: "flex",
              flexDirection: "column",
              gap: 12,
              maxWidth: "48rem",
            }}
          >
            {/* Earlier message — toolbar hidden until hover or focus (pinned to its hover state here) */}
            <UserMessage
              content="First message — hover to reveal the toolbar."
              timestamp={new Date(2026, 3, 1, 16, 35)}
              revealToolbarOnHover
            />

            {/* Latest message — toolbar always visible */}
            <UserMessage
              content="Latest message — toolbar always visible."
              timestamp={new Date(2026, 3, 1, 16, 40)}
            />
          </div>
        );
      }

              timestamp={new Date(2026, 3, 1, 16, 40)}
            />

            {/* Copy + retry */}
            <UserMessage
              content="Can you look at this?"
              error="Message not delivered."
              onRetry={() => {}}
              timestamp={new Date(2026, 3, 1, 16, 41)}
            />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Internationalization

    The action toolbar owns these localized strings:

    * `ai-kit.messageToolbar.copy`
    * `ai-kit.messageToolbar.copied`
    * `ai-kit.messageToolbar.retry`
    * `ai-kit.messageToolbar.userActions`

    Localize `content` and `error` before passing them. Mount `AiKitIntlProvider` inside `CartoTheme` to switch the toolbar strings.

    ## React Accessibility

    * The toolbar groups user message actions under a localized name.
    * Timestamp is always present in the toolbar.
    * Hover-hidden toolbars remain reachable from the keyboard.

    ## `UserMessage` Props

    The `UserMessage` accepts the following props and forwards remaining `<div>` attributes except `children`, HTML `content`, and `style`.

    <ParamField path="content" type="ReactNode" required>
      Message body. String, inline markup, or a Markdown tree.
    </ParamField>

    <ParamField path="timestamp" type="Date | string | number" required>
      Send time. Accepts a `Date`, ISO string, or epoch number.
    </ParamField>

    <ParamField path="copyText" type="string">
      Source text for copy. Takes precedence over a string `content`.
    </ParamField>

    <ParamField path="error" type="string">
      Error line below the bubble. Omit or pass empty to hide it.
    </ParamField>

    <ParamField path="onRetry" type="() => void | Promise<void>">
      Retry a failed send. Surfaces only when `error` is set.
    </ParamField>

    <ParamField path="revealToolbarOnHover" type="boolean" default="false">
      Hides the toolbar until hover or focus. Touch always shows it.
    </ParamField>
