+ * Performs a deep structural equality check across all provided arguments.
+ * Returns true only if every argument is deeply equal to every other argument.
+ * Handles primitives, arrays, and plain objects (JSON-like) recursively.
+ *
+ * Non-plain objects (Set, Map, Date, etc.) are compared by reference only,
+ * since Object.keys() does not enumerate their contents.
+ *
+ * @param args - Two or more values to compare for deep equality
+ * @returns True if all arguments are deeply equal
+ *
+ * @example
+ * ```ts
+ * deepEqual({ a: 1 }, { a: 1 })           // true
+ * deepEqual([1, 2], [1, 2], [1, 2])       // true
+ * deepEqual({ a: 1 }, { a: 2 })           // false
+ * ```
