+ * Sanity’s Image component is a wrapper around the HTML image element.
+ * It supports the same props as the HTML `img` element, but automatically
+ * generates the srcSet and sizes attributes for you. For most use cases,
+ * you’ll want to set the `aspectRatio` prop to ensure the image is sized
+ * correctly.
+ *
+ * @remarks
+ * - `decoding` is set to `async` by default.
+ * - `loading` is set to `lazy` by default.
+ * - `alt` will automatically be set to the `altText` if passed in the `data` prop.
+ * - `src` will automatically be set to the `url` if passed in the `data` prop.
+ * - `lqip` is set to `true` by default.
+ *
+ * @example
+ * A responsive image with a 4:5 aspect ratio:
+ * ```
+ * <SanityImage
+ *   data={data.image}
+ *   aspectRatio="4/5"
+ *   sizes="(min-width: 45em) 40vw, 100vw"
+ * />
