      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

    To use the `GuidanceCard`, pass a `referenceLabel` and ordered `changeSections`. Wire `onApply`, `onEdit`, and `onDismiss` to handle Accept, Edit, and Reject.

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

    function ExampleComponent() {
      return (
        <GuidanceCard
          referenceLabel="Estimate #12345"
          changeSections={[
            {
              type: "single",
              changes: [
                {
                  id: "labor-hours",
                  label: "Labor hours",
                  from: "6.5h",
                  to: "8.0h",
                },
              ],
            },
          ]}
          onApply={(ids) => apply(ids)}
          onEdit={(ids) => edit(ids)}
          onDismiss={() => reject()}
        />
      );
    }
    ```

    ### States

    `state` is `"default"`, `"accepted"`, `"rejected"`, or `"skipped"`. Non-default states collapse the body unless you set `defaultExpanded`. Accepted state can filter visible rows through `appliedChangeIds`.

    <LiveCode showCode example="ai-kit-guidance-card-states" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { GuidanceCard } from "@servicetitan/anvil2-ai-kit";

      const sections = [
        {
          type: "single" as const,
          changes: [
            { id: "labor-hours", label: "Labor hours", from: "6.5h", to: "8.0h" },
          ],
        },
      ];

      function App() {
        return (
          <div
            style={{
              display: "flex",
              flexDirection: "column",
              gap: 16,
              width: 530,
            }}
          >
            {/* Default — interactive review */}
            <GuidanceCard
              referenceLabel="Estimate #12345"
              changeSections={sections}
            />

            {/* Accepted — collapsed summary */}
            <GuidanceCard
              state="accepted"
              referenceLabel="Invoice #1234"
              changeSections={sections}
              appliedChangeIds={["labor-hours"]}
            />

            {/* Rejected — collapsed summary */}
            <GuidanceCard
              state="rejected"
              referenceLabel="Invoice #1234"
              changeSections={sections}
            />

            {/* Skipped — collapsed summary */}
            <GuidanceCard
              state="skipped"
              referenceLabel="Invoice #1234"
              changeSections={sections}
            />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Selection

    Multiple single changes each get a checkbox. A single change has no checkbox; Accept applies to that item.

    <LiveCode showCode example="ai-kit-guidance-card-selection" screenshot fullWidth>
      ```tsx lines expandable theme={null}

            }}
          >
            {/* Multiple changes — each row gets its own checkbox */}
            <GuidanceCard
              referenceLabel="Estimate #12345"
              changeSections={[
                {
                  type: "single",
                  changes: [
                    {
                      id: "labor-hours",

                      from: "6.5h",
                      to: "8.0h",
                    },
                    {
                      id: "labor-rate",
                      label: "Labor rate",
                      from: "$95/hr",

                },
              ]}
            />

            {/* One change — no checkbox; Accept applies to the sole item */}
            <GuidanceCard
              referenceLabel="Estimate #12345"
              changeSections={[
                {
                  type: "single",
                  changes: [
                    {
                      id: "labor-hours",
                      label: "Labor hours",
                      from: "6.5h",
                      to: "8.0h",
                    },
                  ],
                },
              ]}
            />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Change sections

    Use `type: "single"` for scalar diffs and `type: "table"` for labeled line-item tables. Table cells may be a string, `{ type: "text", value }`, `{ type: "diff", from, to }`, or `{ type: "addition", value }`.

    ### Reference link

    Pass `referenceHref` to make the reference label a link.

      ```tsx lines expandable theme={null}

      }

      export default App;

    </LiveCode>

    ### Actions

    Accept and Edit receive the currently selected single-change and table-row ids. Reject calls `onDismiss` with no selection.

    ## Internationalization

    `GuidanceCard` owns these localized strings:

    * `ai-kit.guidanceCard.suggestedChanges`
    * `ai-kit.guidanceCard.suggestionsAccepted`
    * `ai-kit.guidanceCard.suggestionsRejected`
    * `ai-kit.guidanceCard.suggestionsSkipped`
    * `ai-kit.guidanceCard.accept`
    * `ai-kit.guidanceCard.edit`
    * `ai-kit.guidanceCard.reject`
    * `ai-kit.guidanceCard.reasonPrefix`

    Localize `referenceLabel`, change labels, reasons, and table headers before passing them. Mount `AiKitIntlProvider` inside `CartoTheme` to switch the built-in strings.

    ## React Accessibility

    * Title text reflects the current `state`.
    * Multiple changes expose selectable rows. A single change applies without a checkbox.
    * Table groups use the kit table selection semantics, including localized select-all and select-row labels.
