MentionContentReact.ComponentProps<typeof MentionPrimitive.Content>—Accepts every prop supported by `@diceui/mention`'s `Content`, including its children. The wrapper renders content inside `MentionPrimitive.Portal`, adds `data-slot="mention-content"`, and merges `className` with popover and animation styles.

Accessibility
- Use `MentionLabel` to provide a visible label for the mention input when the surrounding context does not already label it.
- Keep the primitive's keyboard navigation and highlighted-item behavior intact; do not replace the provided `MentionInput`, `MentionContent`, or `MentionItem` with unstructured elements.
- Ensure suggestion item text is descriptive and distinguishable when multiple people have similar names.
- The content is rendered through the primitive portal, so verify that it remains visible and positioned correctly in dialogs, clipped containers, and other stacking contexts.
- The default styles include visible focus treatment, disabled opacity, and disabled pointer-event behavior; preserve these states when overriding `className`.
