2 * One slug rule for every site: accents folded to their base letter (café → cafe), every run of anything else that is
3 * not a-z or 0-9 made one hyphen, no hyphen at either end, and at most `max` characters, cut back to a whole word when it
4 * can be. The empty string when nothing is left, so a caller with a fallback writes `slugify(x) || "entry"`.
5 *
6 * @param {string} text
7 * @param {{ max?: number }} [options]
8 * @returns {string}
