````javascript
function run(selected_text) {
  const lines = selected_text
    .split(/\r\n?|\n/)
    .map((line) => line.trim())
    .filter(Boolean);

  function naturalCompare(a, b) {
    const chunksA = a.match(/\d+|\D+/g) || [];
    const chunksB = b.match(/\d+|\D+/g) || [];
    const count = Math.max(chunksA.length, chunksB.length);

    for (let index = 0; index < count; index += 1) {
      if (chunksA[index] === undefined) return -1;
      if (chunksB[index] === undefined) return 1;
      const partA = chunksA[index];
      const partB = chunksB[index];
      const numericA = /^\d+$/.test(partA);
      const numericB = /^\d+$/.test(partB);

      if (numericA && numericB) {
        const valueA = partA.replace(/^0+(?=\d)/, "");
        const valueB = partB.replace(/^0+(?=\d)/, "");
        if (valueA.length !== valueB.length) return valueA.length - valueB.length;
        if (valueA !== valueB) return valueA < valueB ? -1 : 1;
        if (partA.length !== partB.length) return partA.length - partB.length;
      } else {
        const foldedA = partA.toLocaleLowerCase();
        const foldedB = partB.toLocaleLowerCase();
        if (foldedA !== foldedB) return foldedA < foldedB ? -1 : 1;
      }
    }

    return a < b ? -1 : a > b ? 1 : 0;

  return [...new Set(lines)].sort(naturalCompare).join("\n");
