+/**
+ *
+ * 사용자 입력을 받는 기본 입력 컴포넌트입니다.
+ * Tailwind 스타일이 적용되어 있으며,
+ * 에러 상태, 아이콘 표시, 컨테이너/내부 커스텀 스타일 등을 지원합니다.
+ *
+ * @component
+ *
+ * @example
+ * ```tsx
+ * import {User} from "lucide-react";
+ *
+ * <Input
+ *   id="username"
+ *   placeholder="Enter your name"
+ *   Icon={User}
+ *   error={true}
+ *   containerStyle="w-full"
+ *   innerStyle="text-sm text-gray-900"
+ *   iconStyle="text-gray-500"
+ * />
+ * ```
+ *
+ * @param {object} props - Input 컴포넌트의 속성
+ * @param {"text" | "password" | "number" | "email"} [props.type="text"]
+ *   입력 타입 (기본값: `"text"`)
+ * @param {boolean} [props.error=false]
+ *   에러 상태 여부. `true`일 경우 테두리가 빨간색으로 표시됩니다.
+ * @param {string} [props.id]
+ *   입력 필드의 고유 ID. 없을 경우 `useId()`로 자동 생성됩니다.
+ * @param {React.ComponentType<React.SVGProps<SVGSVGElement>>} [props.Icon]
+ *   아이콘 컴포넌트 (예: Lucide 아이콘). 왼쪽에 표시됩니다.
+ * @param {string} [props.containerStyle]
+ *   상위 `<label>` 컨테이너의 추가 Tailwind 클래스명
+ * @param {string} [props.innerStyle]
+ *   내부 `<input>` 요소의 추가 Tailwind 클래스명
+ * @param {React.ComponentPropsWithoutRef<'input'>} [props.rest]
+ *   나머지 HTML `<input>` 속성들 (예: `placeholder`, `value`, `onChange` 등)
+ *
+ * @returns {JSX.Element}
+ *   스타일이 적용된 입력 필드 JSX 엘리먼트
