+/**
+ * Creates a function that removes duplicate values from an array, preserving
+ * the order of first occurrence. Equality follows SameValueZero, matching
+ * Set semantics. Use it with {@link pipe}.
+ *
+ * The returned function is lazy-capable inside {@link pipe}. It keeps a Set of
+ * values already emitted during each pipeline run.
+ *
+ * @template T - The type of elements in the array.
+ * @returns A function that maps a readonly array to a duplicate-free array.
+ *
+ * @example
+ * import { pipe, uniq } from 'es-toolkit/fp';
+ *
+ * pipe([1, 2, 2, 3, 3, 3], uniq());
+ * // => [1, 2, 3]
